Newby question here, but I'm trying to learn as I go... I have my single cab stripped down and in epoxy primer. As I now sand off areas of primer for welding etc., what's the base way to cover the bare metal when I walk away, rattle can primer? it seems like a hassle to be mixing up epoxy to spray over little spots here and there, every day. Thanks in advance for any knowledge you can drop on me.

it's a good idea as long as you can use it up, it's only good for a couple days after it's actuated.


eastwood has a roll on epoxy primer, still have to mix it, but no gun to clean.

This one is new technology and you do not have to use it up within 6-8 hours like the Spraymax 2k aerosols. You can put this one back on your shelf and use the rest later.

Are you sure? Once the reaction has started you're not stopping it. Unmixed parts certainly have a long shelf life though.

It has been out for like 2 years. I believe they are out of Canada. You can buy some on Amazon and check it out. They have top coats too:

I sprayed my gas tank in the satin black a few weeks ago.
