FC7 Plum Crazy Purple paint question
hey so quick question and not to sidetrack but do you guys block sand the sealer?
Yes and no, you only block sand fully cured primer, a sealer coat is used as an optional first coat when painting to fix minor imperfections that may have been missed during prepwork, and to make the car one consistent color so that transparent or semi-transparent topcoats cover evenly or quicker; technically, sealer is a thinner version of primer/surfacer. That being said, when I was painting a complete high end job, after I was satisfied that my primer was blocked and finished to perfection, I would spray a coat or two of sealer over the entire car to make it a consistent color, fix any minor burn throughs etc. and let it dry. Then I would wet sand the entire car(using a soft block) with 600 wet. I was taught(and fully believe) that if you prep your surface properly, you do not need a sealer coat before starting to lay down your color coats, and in a wet on wet paint application(ie every paint job) the less coats you put on the better your overall final finish will be, the nicer the metallics will lay, and the smoother the clear will lay down also.
This was just my way of painting, by no means do I say that its the only way, I just found that this way gave me the best results, especially when spraying candies.
So I guess if you do it my way, you do actually block sand the sealer :)
