I missed the original thread about care and feeding of gel coat, so sorry if I'm covering old territory. You can put a shine back in gel coat with a light
polishing compound. I like Mirror Glaze. Simonize-- which you may be able to get in automotive stores-- is kinda heavy duty. I've used the same bottle of Mirror Glaze for a couple of decades, because you just need a little, and then some steady muscle to polish up the area. You should be able to get a real light
duty polishing compound in a serious boat supply store or a autosupply store that caters to
If I was doing a big area, though, say a whole door or such, I'd wet sand the whole thing and then use an automotive paint-- just one of those cans from the autoparts store. Without a compressor and I spray booth I can't get a get coat finish I can live with.
I have no loyalty to gel coat. Long ago and just down the road I apprenticed as a boatbuilder. Gel coat is wonderful only because it seperates easily from a mold. It's hard as chalk, but you can keep a polish on it, until you polish through to the glass underneath.
