    Hey all, Since my other post about the McLaren drew up some questions about sanding, I figured I'd post this. This was done as practice, so it was done on a door that was damaged and would be thrown out... no biggie if I burnt through. (I didn't!)

    Anyway, I intentionally scratched the OEM paint with 180 grit sand paper, and through the process of sanding with 400, 600, 1200, 3000, and finally 5000 grit, it came out. along with a pretty impressive amount of clear coat lol. Then it was buffed back to perfection with 3M's three stage polishing system. Enjoy!

    What a nice door...

    Better sand it with 400 grit...The white power is the clear coat that was sanded off...

    Not a problem! The only hard part is knowing when to stop sanding. Of course if you sand through the clearcoat then you have to re-clear it which costs $$$. Trial and error is the best way to learn how to do this stuff.

    Anything over 3000 is usually reserved for high end shit or polishing metals.

    very nice work, I'd be afraid of burning through the clear.

    Good stuff but why so high on the grit #? You should be able to take out 2500 grit with finishing polish

    This sounds like a great idea. My from bumper currently looks like bugs are splattered on it(the marks they leave not the color.) but, it's clean.
