Hey all, im the guy with the 30 scarab over hull project. I thought I would set this little thread up and get everyone’s opinion on how to correctly wet sand a gel coat hull that is 20 some years old.
My hull is chalky, kind fo shinny in places, and rough in other places. I have a red stripe along the hull that has scuff marks, scratches, and gouges that have not gone all the way through the paint, but need to be sanded out. I was planning on wet sanding my hull and bringing that old gel coat back to life. I have read that you can really restore Gel coat.
Now, I have read not to use anything over 800 GRIT wet, and I have read that Mr. Oop’s used 600 grit DRY, and now I am confused…..I was planning on doing 600 wet, then 800 wet then up to a 1000. However I don’t know if im going to mess it all up. I THINK Gel coat is pretty forgiving, however this is my assumption, some reassurance from an experienced person would help!! Like I said I was going to do the entire thing (30 ft) and I really need to hear from someone who has done this and knows tips tricks and can build my confidence. Items such as pre cleaning? Do you NEED to apply acetone first? Or other questions in regards to what to look for and what to expect when sanding. Your expertise needed:
