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 http://www.trilliumrv.com/
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.
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.
