    Wet sanding help..

    Hey fellas, I'm doing a Grand Prix GTP 04 black, there's a lot of little marks in the hood, I'm guessing it's from rocks hitting the clear coat and putting "dents in it" if that makes any sense lol it's not in the primer..So I'm new to wet sanding..So I gave it a shot, I used 3m 2000 grit sand paper, I went up and down motion a couple of times...then used UC with polishing pad and the marks are still there and now with some scratches from the sand paper, I ran the UC again over it, same result, so I then went to the wool pad to get out the swirls cause the polishing pad wasn't...bad idea that made the CC very hazy and swirls galore. I went back to the UC with polishing pad and I ended up back at square one, those little dents" and now very slight swirls..For some reason I cannot used a more aggressive pad the car screams swirls lol any help??

    Im I'm using a Makita rotary

    Also so I'm going to be buying a G100v2 should I get the sanding pads and so forth? Can anyone tell me exactly which ones to get please??

    STOP USING THAT ROTARY! !

    And don't try something on your car that you've not done before, get you a test hood and test on it!

    And get a G110 before you have a bad day!!!

    Have any pics to show condition and what your looking at?

          All those little cracks are clear coat failure. They are called crows feet or lacquer cracking and the only way to fix that is with a repaint

            Hey sky

            Evan's right about crows feet/lacquer checking that's found in single stage paints, but clear coat failure it's not, (I've got first hand experience with that on my old jeep cherokee) Only thing to do besides as Evan told you is a repaint but you can do the cleaning polishing and of course the most important thing sealing it!

            I believe BillyJack has the same problem when he see's this he will be a great source as to help you maintain this problem.
