Take a refrigerator magnet, a thin one like a rock auto one!
They are better than any bondo or paint thickness checker any day!
They will fall off or not sick good even if there is extra paint!
And never buy on of these cars unless you check the frame fully ! I had a absolutely rust free
Accident free gs but the frame was cracked in four places! One spot 3/4 of the
Way through ! And take a friend they might see something you over look! If you can drive
It have them fellow you to see if car goes straight down the road! Good luck and let’s hope it is the right car for you!
