Painted Fiberglass Interior

[Patty S.]

Two years ago I had some fiberglass work done inside & outside of my Uhaul. The person who did this work called me & told me he had painted the interior due to the amount of fiberglassing. I am now getting around to trying to make the paint shine like the gelcoat used to shine. The paint is either enamel or acrylic. I have been wetsanding the paint with 2000 grit sandpaper & have buffed it with a good 3M rubbing compound from an autobody shop. Body shop & marine place both told me that after both wetsanding & compounding that it would shine. But it is still pretty dull. Is there anything I could apply that would give it the nice shine that the unpainted walls had. Any help would be greatly appreciated. Thank you

I"ve not repainted a glass trailer, but have done a lot of work on interior and exterior of glass boats. If the paint that was applied was satin to start with, you may never get the shine. Flatting agents are usually added to satin or flat paints to lower the sheen, and you can't bring them up to a gloss finish. That's all I can think of right off.
