View Full Version : How to prep rock chips during body work
02-13-2012, 06:16 PM
I will be getting my truck ready for repaint in the next couple of months or so and I have no idea what to do with the rock chips.The paint on the truck is in good shape just scratched to hell, no dents or dings need to be replaced so I was just gonna sand the clear coat down and respray.However, having wide tires has made thousands of rock chips along the bottom half of the truck.Im not sure whether to sand them all the way to the metal or fill them with glazing putty.
What do you guys suggest?

Sand them out. Otherwise you will get a chip in the new paint and it will be twice as deep.

so pretty much take it all the way down?

don't have to go all the way, depends on how deep they are. I usually just use 220 on a DA and take em down until they are smooth to the touch all around, some may go bare metal some may not. If they go bare metal hit them with some self etch primer. Reg. primer won't do it, they'll rust under the primer.

Just remember if you have numerous chips to metal, by the time you try to feather back the chips individually you also are creating low spots. If there are literally hundreds of chips I would sand the entire area to keep the surface flat.

Yeah I was just seeing what people thought as I have seen people fill them in with glazing putty.
