what grit sandpapers and type of polishes for best result
Kevin,
What brand and type of urethane did you use. If you used a high solids
urethane then you have enough to cut and buff. If not you may be kind of
thin with only two coats. I typically use Deltron and apply three to four
coats. I plan on color sanding practically everything. Not because of dust
but to get the desired deep finish.
If it is a lot of dirt you may want to color sand with 600 grit then apply
another good wet coat.
I have found that the bulk of dust in paint jobs comes from two places: 1)
Your clothes! Use a new disposable paint suit every time. 2) Door jambs and
little nooks and crannies. I always blow the cracks and crevices out and
tack the car off two or three times before I paint.
If it is just scattered dirt I would suggest getting a nibbing block and
"nibbing" the tops of the dirt first then color sand with 1200 grit. Keep
water running over the surface while you sand. If you sand it slick in one
place you need to sand it all slick or when you buff it some spots will have
no orange peel while others still have orange peel.
3M makes a great series of color sanding paper, polishes and cutting
compounds. Some of them can hurt some finishes. Check with your supplier for
their recommendation for the specific paint you bought.
