are you supposed to sand after blasting i had no idea. I used ppg metalprep i cant remember the number. I already used all of my ncp on the customers whole car so how could ppg tell if i had a bad batch and how can i tell if i get a bad batch. I wish i could just start over from the beginning but it is a customers car and i simple can't aford to re do it and the boss sure as hell won't. 1 year ago the painter at the shop i work at quite so guess who got to be the new painter. I went to wyotech were i was in a paint class but i never wanted to do it for a living so i was focusing more on my other classes, so any help or advice you can give me would be great. One more thing is it normal for your health to nose dive after you start painting. It's hard to breath, i feel light headed alot and get way more headaches than i used to before painting, andf feel overall slugish. just another sleepy eyed painter i guess
