On coatings...

What i've read : )
Since if follow (near daily) my long time acquaintances at both Expedition Portal Forum & Sportsmobile Forum i've read through lots of DIY threads/projects.

I remember reading of at least one project that utilized the Grizzly Grip product both inside and outside their rig (might have been a cargo conversion?). Anyway, what i do remember is they used the "Aromatic Polyurethane" version on the interior walls, and the "Aliphatic Polyurethane" version on exterior running boards/fenders. You just roll it on with their special textured rollers and you have a nice washable surface once dry. The Aromatic remained flexible (for interior use) and the Aliphatic became rigid like the typical truck bed liner.

Cari & I will be ordering the "Aliphatic Polyurethane" version and applying a matching coat of black to the exterior running board areas of both van and trailer this spring.

Cheers,
Thom

OH...PS...i remember painting the interior wood framing of our A liner with some fancy marine grade wood preserver...It nearly knocked us out for the next season sleeping inside the rig! Sooo...always research any product such as GG or paint, etc and see if it is toxic/smelly!

1974 Boler Resto. Oops, I did it again...

"Farmer,
Hulliner does NOT stretch like "rat fur," so working the corners is tricky. You have to carefully plan out your cuts. I was able to hide a lot of seams behind cabinetry. And where seams are visible, butting two very clean and straight edges together doesn't look too bad.

(BTW, Reflectix as an insulator is more efficient WITHOUT a wall covering over it. So, hidden wall areas are better off uncovered.)
"

So it seems using the hull liner may have the same issues with creases, edges, as the non porous vinyl. Hmmm....

I have a cushion made from some pretty stretchy and soft fake leather. I think it would work, I wonder how this Nauga Soft Vinyl compares?

Coating a porous material like rat full would probably end up darn heavy and I'm dubious that you'd get an attractive finish. I have thought about just gluing a non porous material on top of my rat fur, but I think it's best for "freshness" to remove it entirely. May take most of my reflectix with it however. I think the fur is bonded to the reflectix better than the reflectix is to the walls.

But the little trailer, while always having been a bit stuffy, is smelling a little extra lived in lately. Not bad, but not fresh. Add the fact that it looks old and ratty, the seams were not handled elegantly by the factory and man, I'm ready for new walls and ceiling! I may try using some 1/8" poplar plywood with the right trim to make a ceiling. It's very thin, light and bendable. One side is high quality, stainable, free of knots, etc.

Thanks, Dylan...

I've always been a bit dubious about fabric-like walls, mostly due to an apprehension that they're more likely to catch and hold odors. And since I'm one of those that cooks inside all the time- and use some very odiferous ingredients- non porous and washable is the name of my game!

I like being able to literally hose out my Trillium, but I'd like it a lot better if the walls were not just washable, but insulated!

Back to the scheming phases...

well I'm confused. Must be different stuff

"HullBlanket Headliner Hull Liner Carpet Type Ivory M93 72” is a beautiful, non-vinyl headliner. Perfect for marine environments, HullBlanket fabric is durable, stain-resistant, mold and mildew resistant, anti-static, and moisture proof. This 100% polypropylene fabric is directional (clear warp and fill orientation) and has a soft, knobby woven look, similar to outdoor carpet.
HullBlanket is easy to work with as it cuts without fraying and is great for use on uneven surfaces because it stretches and contracts during installation. Sews easily with a V-69 thread and #20 needle.
To install, spray 3M General Trim Adhesive on both surfaces.
Width: 72 inches
Weight: 14 oz. per square yard
Thickness: 3/16 inch

sounds just like the stuff we used too Raz (& linked to)

quote:
Marine Hulliner is a very durable carpet material designed for the inside of boat hulls. It has a Geometric Style Pattern (carpet feel with raised bumps). Can be used for headliners, wall coverings, etc... in Motor homes, RV's, and other applications.

SPECS:
  • Width: 72" Inches Wide
  • Non-backed Needle Punched Carpet
  • Durable: Stands up to the marine environment.
  • Excellent Colorfastness: Resists fading from the Sun's UV Rays.
  • Resists Stains & Soiling: Easily cleaned.
  • Easy to stretch, cut, fit, and mold to desired shape or size.
  • Resist mold & mildew.
  • Will not fray or unravel.
  • ...end quote"
In context of Raz's post i think (& what Raz might have been pointing out) is that this sort of marine grade "Hull Liner" fabric is designed for just what we are asking it to do inside our Eggs. And in the two+ years cari & i have had our hull liner on the walls in the van we have yet to notice any _stuff_ clinging to, or messing up, the fabric. We've not _maintained_ it in any way. Not even brushed it off. Looks nice and clean as the day we installed it. And no smell or anything. Though all we ever do inside as far as "cooking" is boil water.

Well- now that it's been said twice, I guess we know what "hulliner" is!

But that still leaves the question as to how it differs from whatever it is that's going in to trailers...

What exactly is the "rat fur" everybody seems to have???

Google is no help finding a definition/makeup, or even a site selling that one...?

LOL. Hey, i'm trying to get my post count over 100

I was inside a Casita two weeks ago in the Costco parking lot here on the Oregon Coast and whatever they had inside there 2007 casita looked very close to what raz & i have linked to. I have no idea what "Rat Fur" is. Sure doesn't sound like a Nautical name, though they did have rats aboard back in the day.

Post-count padding, eh?

O.K- I'll help!

Question to the crowd:

If the stuff that goes on the walls of "fuzzy-wall trailers" isn't hulliner... what is it???

WARNING:

The first person that says "rat fur" is gettin' a knuckle sandwich. Except Derek-who's-working-on-post-count, that is...

THIS is rat fur and it's on many if not most Scamp walls.

Tan Headliner Wall Fabric (Per Sq. Yd.)

It's fuzzy, not carpet, has no strong backing and thus can be stretched.

Odors are an issue, but so it dust. I want to take my 13' to burning man, which is basically like camping on packed talcum powder. it's super fine and gets everywhere, there is no stopping it. There are white out dust storms of it. That would get so far into rat fur and NEVER come out entirely.

So I'm still looking for that ideal, wipe-able wall covering.

O.K., Campers, listen up!

I actually found a wholesaler for this stuff, they use "hulliner and headliner" interchangeably for the same product, and here's a statement from their website:

Quote:
Note - Supply of this item has been limited. Due to the slow RV and Boat industry, the mill is not running this item very often.
Emphasis mine...

Sounds to me like they're exactly the same thing...unless of course "rat fur" turns out to be something entirely different, perhaps made out of actual rats or something.

well i couldn't have said it better...so here it is. You read it on the internet so it must be true:

The folks in Minneapolis trap the rats and send the frozen carcases up to Backus (obviously, this is only done in winter!). There, the men in town skin and cure the rat pelts. Church sewing circles then take these finely prepared pelts and use ultra-fine needles and thread to sew them into the seam-free fabric used by the Scamp folks to cover the insides of their trailers. It's truly a win-win-win arrangement! Minneapolis lowers its rat population, folks in a depressed part of the state have employment, and Scamp gets a superior product.

You post counter junkies are pathetic. Hey - that got me up to 68!!!

Anyway, I'm smack dab in the middle of lining my Scamp 13 with ensolite type foam, and will then cover it with marine grade off-white vinyl. I'm moving slow, but should have some pics soon.

Next thing you'll be telling us that Casita gets theirs from "desert rats".

And what about Escape? Are rats even allowed in Canada???

and i will say it again (you can even reset my post count to zero!)...

Here is a quote from the link to the "rat fur" / headliner in Francesca's post:

"Marine Hulliner is a very durable Non-Woven carpet material. There is a Geometric Style Pattern and a plain cutpile look called Stratos. Unlimited uses - for Hulliner and headliner in Boats, Motorhomes, RV's, Canopies and other applications.

Features:

  • Width: 6 Feet Wide (72" Inches Wide)
  • Durable: Stands up to the marine environment.
  • Excellent Colorfastness: Resists fading from the Sun's UV Rays.
  • Resists Stains & Soiling: Easily cleaned.
  • Easy to cut, fit, and mold to desired shape or size.
  • Resist mold & mildew.
  • Will not fray or unravel."

This appears to be the same stuff as used in our van build, and IMO, the Parkliner.
And that raz linked to, and me too,
( : and now
Francesca : )


RAT FUR = Head Liner/Hull Liner
Who knows why the stuff ever got the slang of "Rat Fur", but we can now just send peeps to the various online (or local like i found mine) fabric shops selling Hull Liner.

The difference in looks would be the choice between
"Geometric" with lots of little squares or diamonds in pattern
OR
"Stratos" sort of smooth like a "rats fur"


: ) I'm really a nice guy.
