    Default Primer from spray can ruin my base coat?

    Ready for the noob question of the day? Getting ready to paint my micro car and I have the biggest noob question of the day for you all. I managed to find a paint booth that I can use for one day. So to save time Iím hoping I can spray, sand and fill at my house. Now, can I use traditional primer in a can? I know I have imperfections on my car yet but I canít see them. So I was hoping to prime with a spray can, sand and then refill imperfections until itís all filled. My question is if I use a traditional primer/filler out of a spray can will that make it harder for when I start spraying my base coat with an actual gun? Thanks In advance for dealing with my noob questions.

    A spray can is not the best thing you can use.

    That being said, there are epoxy primer spray cans that are two part. You pop a little button in, it breaks and mixes the two parts in the can and then you have 8 hours or so to use it. That is great for direct to metal.

    Also there is UPOL High 5, it is a high build primer in a can. It sprays and sands nicely, and I was able to spray over it with simple single stage paint.

    I'm sure the pros here will offer more and probably better info.

    Thanks, I figured itís not the best. I think I may just see if he can let me in a bit early so I can mix up some primer. I appreciate the input!

    There are some two part primers in aerosol cans but it might be a little expensive if you only have a small spot to do.
