Hey guys, I’m going to paint the rear bumper cover for a tri coat pearl white Infiniti 2014. This is the bosses car so he wants it perfect. I will be using ppg envirobase. My question is should I put ppg 2021 clear or should I use ppg 4010? My paint store offers both. They also sell medallion high teck glamor clear. What do you guys think will work out best? Also he bought a used bumper from a bumper shop for less then half the price of retail and it’s black with a few scratches. Should I prime it? Seal it? Or just spray over the old clear? Also should I use 400 or 800 wet to sand out the scratches and ready for paint?
Thanks guys!September 24, 2014 at 3:51 am #47448
I would use either the 4010(low voc of dc4000) or the 2021(great clear and probably the easiest for you to use)
It depends how beat up the bumper is, if there are no chips,scratches etc a quick scuff with 400 and an interface pad on a 6″ palm sander then red scuff pad your edges.I would then proceed straight to a white sealer,base then clear and call it done.
It also depends how carried away you want to get on color match,most tri-stage white vehicles dont even match themselves.(the bumpers,moldings and door handles can be a smorg of different colors)
If you want it to match perfectly you have 2 choices,blend the quarters or do a let down panel to see how many coats of midcoat pearl you need for a match.A let down panel is a spray out divided into 3 sections that will show 2,4,6 coats of pearl so you can match it to the car(plenty of info about them if you search).Good luckSeptember 24, 2014 at 5:34 am #47449
Are their any big differences in the 4010 and 2021? Same shine,depth,life and ease to buff?September 24, 2014 at 5:40 am #47450
Haven’t used any of the 4010,just going by what my local jobber has told me.I have used plenty of 2021,its a great clear.
