Priming my 68 to prevent further rusting....... need help.

[Lost Sheep]

Hey all, I'm planning to sand the nasty green paint on my 68 Charger and shoot a coat or two of primer on the body instead to kinda prevent the rust from continuing until I can afford the quarters/trunkpan this summer. I was wondering if anyone has suggestions on a good primer that is cheap but looks good as well. I would also like to know if there is any primer that I can shoot on the car that is black?

thanks in advance.

you can look into 5star primers, they make a decent cheap product. but it wont hold up as well as a good quality primer like ppg, dupont, or rm

Primers do not seal in fact they may hold water and oils. I'm using Penitrol and its working so far.

I need to do something since I cant afford to replace the rusty panels right now........... and I live in an area where is snows. I currently have spraycan paint that came from the Dodge Dealership on the car but it's wearing off.

I sanded / wire brushed my car and sprayed rust converter on the bad areas which essentially neutralizes it and turns it into black primer. I think I used Rustoleum Rust converter rattle can. like $8 per can. Primer is probably going to cause you more headache since it has large pors for paint to hold onto which means if its outside your probably better off just getting Por-15 or some other rust converter to kill it instead of just cover it up.



But what do I know...

I think your best bet would be to sand down to bare metal (make sure no rust) then spray it with SPI's epoxy

This WILL protect against moisture, as it does not breathe like standard primer. I think the only thing is that it does not handle UV rays very well. But i would give em a call and see what they say.

I have 2 doors painted with this stuff and its awesome. Not like your standard primer.

I agree. Use epoxy, regular urethane primers absorb moisture. Don't even let laquer primer or spray cans cross your mind.

I used PPG epoxy primer then waxed it.
Been good for a year now.Just going to take a couple rounds with the wax and grease remover when I'm ready to continue on with the work.
