And yes, this is pinholes in the filler, not rust. It's all brand new sheet metal with filler applied for straightening the body panels. I only seemed to have created the pinholes in one small area of the roof...but I got a lot of them in that area. So I don't know what I did wrong when I did the filler work.

Also, for Vince, the Evercoat Glazecoat is a typical two part very fine filler...much like "icing". Typically used for final glaze, filling minor low spots, repairing tiny flaws etc. I know it will do a fair job of filling pins because I have used it for that on previous occasions. But it DOES require sanding and another coat of that's what I'm trying to avoid...another round of primer and blocking.

Anyhow, this morning I went out to the shop and embarked on some experimenting with the primer idea. Hopefully I can report back the outcome by tonight.

cboy, your primer idea will work if the pin holes are small, I have done it many times to fill them. I sometimes have even used masking tape over the pinholes to keep the primer from running out if the pin holes are on the sides. just remember they have to be small pin holes. The bigger ones will need puttyed and reprimed for best results. JMO Tim
