Bringing our Trillium 4500 home from the lot for a bit more work on the Memorial weekend.

I'm focusing on the awning/rock guard on the front. It's worn away and dirty, with little fibers sticking out. I read about Chris turning his around and I might consider that, but the logo outline is still visible, and I think I can just fill it in with blue sign paint. I was thinking that after removing the dirt, I might be able to stick down the fibers by painting on a coat of expoxy such as West System. Then the logo painting. Then another protective coat of epoxy.

Any thoughts on that?

Hi Kathleen,
I bought a Trillium 1300 at the end of 2008 that had the same problem with the rock shield.
However, the Trillium logo was not too faded. You might contact
to see if they have any logo decals? Here what I did with it.

Removed rock shield from trailer.
Washed it thoroughly with soap and water.
Polished aluminum frame with fine steel wool.
Washed again.
Lightly sanded with 400 grit sandpaper to knock down the fiberglass fibers showing through.
Blew off dust with compressed air.
Wiped down fiberglass and aluminum with denatured alcohol.
Masked off aluminum frame leaving only fiberglass exposed.
Sprayed fiberglass with many light coats of clear enamel over a several day period.
Removed masking tape.
Reinstalled rock shield.

The shield is not perfect but looks much better than it did and the fiberglass is protected.
The trailer is kept in the garage so out of the sun except when being used. It was on a
six week 4700 mile road trip AZ>UT>NV>CA>NV>ID>MT>WY>UT>CO>UT>AZ last July/August.
I hope this helps.

I had excellent results cleaning and deburring the fibreglass rock guard and aluminium frame with an SOS pad - just use lots of water.

I fnd that the worn bits of fiberglass develop a dark color (mold?) over the winter. A light spray of mold remover (bleach based) brightens it right up. I keep it away from the painted logo as I do not want to bleach out its color.

Thanks for the cleaning tips, Will, Phil and Larry. I imagine I can get it clean, but I think I'm stuck freehanding the logo after reading past threads on the subject.

I will use a clear coat, but since we have been storing our trilly outdoors, I'd better do some more research on that.

Larry, your rock guard looks great. Will post a pic of my project when done.
