I hit it last summer with rubbing compound, and although I'm pleased with the results, still have a little white haze on it. What grit? By hand or sander? Straight lines only with a sanding block? also, how much "wet" in wet sanding? Thanks guys
maybe try a detail shop..... someone who is experienced with a buffer? I gave it a try once on a car and it didnt go so well. I'll leave it to the professionals
So you had some trouble with it, huh? I was hoping it was one of those things not too technical, just elbow grease. Maybe I'll call around then. Definitely don't wanna screw it up!
How gritty you go depends on how much oxidization you have. Lower grit with more oxidization. If you are working on a colored gel coat stripe over white you have to be careful as the colored gel coat is very thin and you can easily sand through it. If it's a uniform color it is easier.
Depending on the rubbing compound it is normally equivalent to 1500 to 2000 grit sandpaper.
I have had success with 1000 grit > 1500 grit > rubbing compound > polish > wax on my old boat and the gel coat shinned like new.
On my jet ski I had to start with 800 grit and then follow the above procedure.
As far as how wet, I would say the wetter the better...
You want to get a spray bottle and wet the surface to be sanded and a bucket of water to wet and rinse the sandpaper. Rinse often, if you have a clump of residue on the paper it can gouge your work. I have only wet sanded by hand. Once you get to polishing and waxing you can use a buffer.
Thanks JM, I think what I'm gonna do is hit it with the compound again, maybe I got lazy last year! It really worked well, I was impressed with the results. Thinking sanding is a last resort. I'm not quite sure we're there yet, like I said there's just a little bit of haze left. Thanks for the schoolin' though!! Hey, as a side note, you had answered my thread on tinting. On second thought I'll post this question over there in case anyone else wants to see it
School me on wet sanding
