Just bought a used hot tub and the previous owner drilled about a dozen reamed holes too many in the siding. It’s definitely some kind of molded 1/2” thick plastic siding with vertical channels. The wife wants to paint the siding so I’m thinking I’ll fill and sand the holes with a q cell mix to clean things up before painting. That said, I have some sun cure Poly or 2 part epoxy.
Which one do you think would hold up under paint, or am I barking up the wrong tree and there’s better products out there?
You might run into adhesion problems, a lot of moulded plastics have a release agent built into them. There will be a primer available that will allow for the use of a resin. Maybe contact the manufacturer to find out what type of plastic it is and go from there.
