    I've wet sanded down to 1500 grit and used automotive polishing compound to gloss it up. Is there a better system to get a high gloss shine on gelcoat?

    I have a 7" air driven polisher, believe the rpm to be about 2500 as recommended, are the electric ones better?
    What do you use for pads?
    What are the steps to get it to a high gloss shine once the area is sanded out with 800 grit?

    JRL Im with stupid

    Anything that will spin at or above 2500rpm will work with AquaBuff. I cant stress to you enough how well this stuff works. Just make sure you keep your part misted while buffing. If it gets to dry you can scratch your plug/mold with the dried up buffing compound. Just make sure you follow the instructions on the side of the bottle. If you do your part will shine with no problem.

    Also, when wet sanding, make sure you clean your mold and change your water everytime you change to a different grit paper.

    Gelcoat shine

    Wet_Foot, 1500 may still be too rough to polish (easily). I had heavy oxidation/fading in both the black and red. I used upto 2500 grit by hand, then 3M polish and 3M wax with a cheap auto buffer. 2000 and/or 2500 grit wet/dry paper at your commercial auto paint store. Do it wet, using a water spay bottle and don't remove too much gel coat. Be gentle, she's a lady. Wash/wipe before buffing.

    will give the aqua buff a shot. I can get the glass smooth and shinny, but can't get it to a high gloss with what I'm using now. After Polishing wet do you just buff it out by hand when dry? Jack, is there somewhere in Canada I can order online to compare with US pricing? thx

    if you look closely there was a spider crack in the rear most bolt hole. Its going together today, then more paint, more anti christ and a lot of soap and water. the wife is banned from the boat until I get the blue dust out.
