Hey guys and gals,
I am prepping my rear differential for some Por-15 semi gloss. I just used the metal prep and I assume it's a light acid that etches the metal for better adhesion... My question is: I rinsed it very well and as you can see it is still very white and powdery... do I rinse and scrub until this comes off?

Maybe a little wire brushing first, but Por 15 really sticks to anything that I've used it on. Can be a little bit brittle, but mostly pretty great over all.
I've even had terrific luck with brush-on Rustoleum Gloss Black on chassis and suspension parts. Lasts forever and really does provide good protection against rusting and rust through.

Nope. That looks great. Just what its supposed to look like.

I will take your word for this because I just read about the "dreaded white powder" and how hard it is to remove and that it was due to getting the acid-treated metal wet before the job was done.
Just a fyi for other searches...I was a bit right... just go with it! I knocked off the loose potassium and blew it off and rinsed again.. right now it is curing and being all happy.
Por 15 goes on great! (like testors model paint) I kept the first coat really thin and neat, I have to wait a week(just my timing, not the manufactures) to see how it cures...I plan on one more coat of Por -15, or see how it looks then some enamal paint for uv protection... So far I like Por-15 better than Rust Bullet... paints better, a little less sticky and less industrial...
Thanks for the help!
