    Default Wet sanding help

    I used 1200 grit on the top of my boat to get out some oxidation, followed by mcguires liquid rubbing compound then mcguires liquid polishing compound. The gel coat looks better than before, but the liquid rubbing compound failed to get all of the scratches left from the 1200 grit, what is a good compound to use after the 1200 grit? Or should I use 1500 or 2000 grit? I can tell that the process is working very well, it's just missing a step. Once those light scratches are out it's going to look bangin.

    Always better to go up a grit but 3m is probably the best compound to use. Should take out 1200 grit scratches. Just make sure you have a good pad and backing plate. I'd do 1500 on a small part then buff and if you're happy do the whole thing. If you aren't happy, go to 2000. Make sure you have good lighting while you're sanding also. It'll help out big time

    I picked up some 2000 grit paper and a 3m 3000 grit foam pad deal, I'll get at it again tomorrow and see how it goes. It already looks good compared to what it was before, just hoping to get a little more out of all my hard work...and hoping to never do this again haha.

    Default Wet sanding help

    It may be over kill but if I'm wet sanding oxidation I usually start with 1500,1800,2000,2400,3400, & final 4000. Then hit it with some 3m.

    It's a chore but the results speak for them selfs.

    Also throw in some dish soap into the water.

    Personally in my opinion Wet sanding is never my first option considering there are a few compounds out there that will do the job with out any wet sanding what so ever , and to tell you the truth oxidation in the gel actually is or occurs from Styrene working it's way to the surface over a period of time .
