How to get rid of pit marks

You might want to try some two part finishing putty. I have recently used some for the first time that is made by 3M. It seems to work well in filling in pitted areas. The proper time to use it though, is before topcoating...not after. See link.

Paddy was worried about bondo cracking from heating and cooling. This would only be of concern on the hood or near the radiator. E-prime is not as affected by the heating and cooling as bondo.

I am thinking that the type of pits Paddy is talking about is rust pits caused by long exposure to the elements. Although it is possible to spot putty them, it would take a lot of putty and time. Primer is the fastest and easiest way of dealing with rust pits, I have found. I used 3M spot putty quite often and it is a very good product.

Set the primer gun in the fridge while your e-prime dries. Use 180-150 grit paper and a sanding block (or DA if you have one), and sand the surface until the area between the pits has most of the primer removed with primer still in the pits.

Fetch your primer gun and prime again. Wait a few minutes and shoot another coat.

Return primer gun to fridge.

Let dry and sand again.

Repeat process unitl satisfied.

Like the instructions say : "Lather, rinse. Repeat."
