mismatching primer.

[RSparky]

I've been told it's not a big deal, but I'm just curious what the mob thinks.

I've got my sharkskinz pieces, and they're pre-primered. Then my tail pieces, which are sanded and ready to be primered, and my new front fender, fresh out of the mold. Then, of course, the shiny red tank with a dent in it that needs sanded, puttied and sealed(?). Then primered...

It's all in different stages right now. But, my question is if i should re-prime my two sharkskinz pieces, or just prime the rest in a similar gray, and hope it matches?

I would prime it all, it will show up as different shades of paint. Ask me how I know.

How do you know

[blue03636]

My tank was a different color/shade of primer, the paint will be darker or lighter pending the primer.

And, dumb question: the new primer will stick onto the old fine, right? I'm not sure what we're using yet, but it will be mixed and all that jazz.

Yes it will stick, just go over it with some 300 grit sandpaper first and it should be fine.

I would prime all the same makes for an easier job. Depends on what your looking for but I prefer a certain primer that works well with the types of paint I use. I would scuff all with 400 and prime. Depending on how you paint might want to scuff again with 400-600. Don't go any high than 600 or risk adhesion issues. Sometimes 400 will leave sanding marks.

Sharks aren't bad but I always re-sand and prime for fear of oils and other contaminants on the bodywork. Nothing like finding an issue after the base coat dries
