David:

I agree -- No question in my mind these stress cracks resulted from either the trauma caused when the tree branch fell, and/or people leaning over on the roof to inspect and repair, in combination with age, etc etc. Here's a picture I took shortly after cleaning out a previous owner's "repair". He used silicone caulk, probably in combination with goose effal and snake paste. By the way, you have a U-Haul, virtually identical to Burro, employing inner and outer shells for superior structural support superior to my (new) trailer, which is a Scamp, and has no inner shell so it relies on a zillion rivets and cabinet support props inside to reduce stress-flexing of the shell.

I do not worry about or expect a perfect color match. I just want it to look re-sellable on the day my survivors have to deal with it. How 'bout a gel product name you like?

Brand names with regards to gelcoat I haven't a clue. I suspect that most of the stuff out there is made by one or two companies and other companies simply buy the stuff from them, put it up in cans, and slap a label on that can and call it their brand. What I would suggest is that you contact any local shop shop that uses gelcoat in any quanity and see if they will sell you what you need. I would suggest you make the request in person (it's harder for many to say no to a face as opposed to on a phone) and be sure to bring your own container. If you are near any shops that do boat work you should inquire there first. You are looking for someone who buys in enough quanity to get a price break and hopefully they will slide some of that price break on to you. Buying a one gallon can off the shelf from West Marine is painfully expensive.

Hope this helps,
David A. L.

I was in West Marine last Friday, and they had gel coat pints and quarts in white, (no gallons) and it was still pretty frightfully expensive, $46 or so.

They did have a gel coat touch up kit with maybe an ounce or two of white gel together with 1/4 oz tubes of pigment in yellow, blue, red and black for color matching. Those were selling 50 percent off at around $15.

Regards,

Matt

Trailer: Burro 13 ft
Posts: 51
I wanted to follow up on my original post. In the end, I decided to paint a center stripe to allow me to re-install the front and back windows as well as my new Fantastic fan and black center rubber edge trim. I will eventually pull the remaining windows and all other shell intrusions to paint the remainder when I have more time. I was very frustrated with the amount of tedious gelcoat repairs that I needed and often had to fill the same holes 3 times due to pin holes.

I ended up using a good quality Evercoat bondo to fill the remaining holes which sanded much easier than gelcoat. After a few coats of primer, I carefully taped off a 3/8" line that followed some of the Burro's natural lines and brushed in a dark brown paint (Dana) that matches the Burro's type. A few days of drying and I masked off the new line as well as the rest of the RV and sprayed the center body with Duplicolor gold engine rattlecan paint. It took 10 cans and easily 15 coats to get decent coverage but cost me maybe $200 in supplies.

If I had more time, i would have removed all the windows and painted the whole egg white and maybe later added some stripes or details. Given my short schedule I made the best of the circumstance. I also liked painting with high quality striping tape and will likely try it on my truck someday.

Repairing pealing gel coat

Hi David,

I have pealing gel coat like the guy at the top of this thread, not quite as much (yet). Thanks for explaining what is caused by. I still don't understand how to repair it. As of now there is NO damage to the fiberglass below.

Plan #1: peel off as much of the gel coat comes off easily, then fill with Marine Tex putty untill level with the old gel coat (or just below) and then gel coat over until it matches the rest of my egg and looks pretty.

problem: you said gel coat will not stick to Marine Tex. So plan #1 seems to be foiled. Similarly people have suggested Bondo which you also shat on.

Plan #2: just peel off the easily pulled of gel coat and fill with a layer or two of gel coat...

Plan #2 does not seem like the best since the voids are a little deep (gel coat layer + some air space before pristine fiberglass, and should require some sort of filler

plan #3: My friend has talked about using epoxy from West systems with some sort of filler, but I was quickly overwhelmed with number of options.

Hello Kevin and welcome to the forum. Unfortunately you have joined a thread that was not active since June of 2010 so I doubt David will respond although you might try sending him a personal message. There are lots of very knowledgeable folks here. May I suggest you post some pictures so folks can seen what you are up against. Good luck, Raz

David, I have fallen off the deep end and will be repairing my cracks this winter (heated garage). Is it OK to paint a dark color on the trailer? I want to paint it like a Holstein (Black and white cow). The trailer will be base white with most of the black splotches around tinted windows. White is boring.

Kyle, I like the paint job.

I am a believer you should do what you want and like... it's your trailer. But, be aware.... all white trailers sell quicker and trailers painted some other color... even accents.... for less money and slower sales... if that's a concern for you.

Look into vehicle wraps. Now days when you see commercial graphics encompassing a car it's actually a wrap. Like a shrink wrap plastic. These are ideal for three reasons.

1. Cheaper than a custom paint job. (considerably from what I've been told)
2. Not permanent. you can peel them off retaining you resale white
3. They actually give a layer of protection against scratches and scuffs.
3.b. They're shiny.

Let us know if you go or look into this route. I'd be interested in knowing if they can do trailer size and it's relative costs.

Cheers,
Mark

You are right in a general way, any time you have something unique you narrow the market, but the good side is that what market is left is way more intense.
I once had a Ford Aerostar with a five speed manual transmission and a few custom mods, I tried to trade it in twice and was offered less that a third of blue-book trade-in value, because it was a stick.
I put a sign in the window and sold it in less than 24 hours for a thousand over blue-book, to someone who really wanted it and knew there was only five similar vans in the whole state.
A cow-camper cud have a very narrow market, but there may be just one buyer who will think it is just toooo Cuetsy-Mootsy to pass up at any price, and you can milk it for all it's worth! One highly interested buyer can make a bull market!
Don't forget the "Cow upholstry" that would make it Udderly fantastic!
Just hope that one potential buyer who wants it isn't lactose intolerant!
