i counted 3-4 paint jobs her, i took it all the way down to sheet metal on the rust mitigation and then went an addl back 4inches or so. When i was at paint shop picking out color for the car, the guy said its probably best to take it down beyond the latest paint job, smooth it prime it and shoot it
but we will see...................
if i have time after work today i will pull the front and rear bumpers and get the grill out so i can clean it up and prime it
