Using PPG over Rustoleum Automotive Primer

Using PPG over Rust Bullet

I am finishing up a swing out tire carrier for my Tacoma.

I have 3 coats of Rust Bullet down currently. I am wondering if I can use Rustoleum Automotive Primer over that and then use PPG Deltron over that.

It sorta feels like I am asking for trouble doing that.


What primer should I use between Rust Bullet and the PPG Deltron(040 Tacoma Super White)? I already have a few hundred in paint alone for the bumper, not really wanting to mess it all up with the improper primer.

Thanks,

Well after a lot of googling it seems like a bad idea. I think I might just apply the PPG base coat right over the Rust Bullet. Hopefully it will adhere well. The only thing that I don't like about it is that Rust Bullet has a bit of an orange peel to it since its such a thick paint to spray. Hope it sticks!

Since we all like photos.

Nice Bumper...

I can't say I've done what your proposing, but I can say this...PPG products like to work with PPG products.

I think before you get too far along, consider doing a 360 and going with PPG epoxy primer and a good PPG top coat and clear. You will have to sand down the rust bullet, but the plus side is you will never have to worry about rust again, ever. The new epoxy primers are the way to go these days and PPG just happens to make the best one out there.

As a side benefit, you could put 3 coats of primer on with 15 minute flash periods. Then let it sit for an hour and put 3 coats of top coat on with 20 flash periods. In an afternoon your done...then you have to put 5 coats of clear on the next day.

That's what I would do. Since your in Florida, it more important to guard against the moisture than the rocks...

Thanks for the response.

If I could do a 360 I would. But after 3 coats of Rust Bullet I don't think there is a going back. This stuff is super hard to get off. I could get it off of the larger flat areas but I could never get it out of all the nooks and crannies.

This stuff is a tough as nails...I think I would have to get the bumper all sand blasted and the blaster would prob wanna kill me.

In the future I will just use the Epoxy Primer (from PPG) and be done with it. But for now I have to fix my conundrum.

Do you think it would be wise to use like a high build primer from PPG between the Rust Bullet and the Base Coat? Or just try and shoot the base coat right over the Rust Bullet? Seems risky either way...

Checked with Rust Bullet and they recommend a high build primer between RB and the base coat. Picked up 2k PPG Primer this morning ill report how it turns out. Thanks again...

Yea, let us know how it goes...

Turned out well for now... 10 Layers of paint.

3 Rust Bullet
2 High Build Primer (2k PPG)
2 Base Coat Tacoma Super White (PPG Deltron 040)
3 Coats of Clear (PPG MC270)

Followed everything to a T on the PPG tech sheets. Ill report back in awhile to give an update..

That looks great. It should last you a good long time.

X2. I agree completely.

I too really like the PPG EP. Now that I've used it a little, pounded on it with hammers, etc. I like it even more. Even the newer California EC stuff is working really well for me.
