Primer question

[caduceus]

I'm restoring a Chimaera which needs a full respray. I haven't yet chosen a colour (but will choose silver if I can't decide on something) but I'm getting close to parts of the car (under rear bumper) being ready for primer.
My question is, can I not primer a car until I have chosen a paint, because some paints react with certain primers? Or will 2k primer be ok for ANY paint?
I only ask as I'd like to get some primer on the underside rear so I can put the exhaust back on for now.

Thanks in advace

It's probably not 2k, but yes.
It's rattle cans and Celly which cause problems, but even then you can spray a barrier coat over them.

Are you going to be painting the vehicle yourself or getting it professionally done?
If the latter I'd suggest you take advice from your chosen painters.

I only use 2k primers & have had no issues overcoating with acylic or waterbase colour coats/top coats & 2k clear as required.

Myself.
Thanks for the info. For the rear underside I'll just get a can of 2k primer. It's not an area that will be seen other than myself and a TVR garage come MOT time.
The rest of the car I'll be using a Devilbiss Pri Pro for Reface and primer, and a Dev FLG 5 for base and clear.

Its worth noting that primer (and filler) is pretty hygroscopic so if you have the car in a damp environment it’ll absorb moisture from the air. Meaning microblistering once its topcoated!

Yes, I was worried about that. It'll get a good baking in the oven before the main primer goes on. Will also get some IR lights on the panels before hand.
