The Great White Brick - '69 Valiant
I have seen this happen to the best of them, And to ask what would do this could be allot of thing's from paint mix ratio to time between coats and allot of things I do not know.
Like gun settings and air pressure to humidity and temperature.
And some time's
the thinner my not let it lay down because of it drying to fast.:dontknow:
It is an art and very hard to be consistent.
Catch it when it is green !! or before it get's real hard. in the next 3 to 8 day. and wet sand it down with wet sand paper and sanding block. not going to say what grit to use he or you can determine that. some where around 1000 ultra and in some of the bad heavy area's start with 800 then go to 1000 ultra,then buff.
It will sand and buff out. You will want that dun anyway, for a merrier finish.
All is good and can be and will be a good finish paint job.
Got any picture's yet?
