I have been following various threads on restoring the shine to a fiberglass boat or camper, and the consensus is that it is a three step process. Clean and degrease, remove the "chalk", coat with floor polish.
Apparently through years of experimentation or desperation people have discovered that ZEP Hi-Gloss wet-look floor finish will make your fiberglass shine.
Now for a confession: I skipped step two. After power-washing the Scamp and scrubbing most of the grime off the next step is to scrub some more with Barkeeper's Friend. It is a powder, like Comet, but safe for fiberglass. this seemed like it should require power tools, and I promise I will get to it soon, but I wanted to see if the $30.00 gallon of floor polish would really work as advertised.
What do you think? The picture shows only one coat. Since I'm going to scrub it off I stopped at one coat, but the blogs say to use several thin coats for maximum shine. Check back in a few weeks to see the final 3-step results.
