any known problems with spraying cellulose paint over hammerite red oxide primer?

going to strip all the paint off my axle and re do it, want some sort of anti rust primer obviously, so while i bought some paint stripper i picked up some red oxide primer to brush on first.

now worried they might react funny and look like crap AGAIN! really don't want another crap finish. want to get it rebuilt!

I've had problems spraying anything over hammerite primer. I won't be using hammerite primer again, except if I want to paint over it in hammerite.

I had a trials off roader which had the hardest paint I have ever seen. It just wouldn't scratch. When I asked the prev owner why, he told me he used Hammerite thinners in the paint by mistake.
But, I have used the new formula hammerite and found it crap. I needed to bake bits just to harden the paint.
I would not risk anything, unless you love prepping.

Do you really need an anti-rust primer? If what the can says is true, just paint it on to bare metal?

So you're going to brush the primer on and then spray over it?

Like I said, I wouldn't bother, esp for an axle. My entire Cobra chassis is hammerited or Pur'd with a brush and looks fine to me!

was thinking of doing it that way yeah. thing is, my axle can be seen from the back when all the bodywork's on, so needs to look nice i'm doing it fluorescent orange you see

Excellent!

I would paint a piece of metal with the hammerite primer and then spray it and see what sort of a finish you get.
It's a shame that Hammerite don't do florescent paint isn't it.

thats how it was before it all started reacting badly and i had to strip it all back off... also a weld needed re-done

just put a light dust of etch primer on there out a can. hopefully that'll work...
