I have some aluminium radiator shroud parts that I wish to paint matt or semi gloss black. Can I use something like Tremclad High Temperature spray paint ? Do I need to prime first and if so with what? Tremclad High temp paint specs do not say if priming is needed before spraying it onto aluminium.
I would value your experience on this including names of black heat resistant aluminium spray paints you have had success with!

Go to Lordco and get some pro form self etching primer ,scrub the alum with scotch bright and wash with dish soap and water , wipe with acetone ,paint away
Alodin is the proper treatment but not nessacary
One part paint 1k air dry is ok but not very chemical resistant compared to a 2 part 2k
Tremclad is 1 part more for lawnmower but ok
A spray bomb for automotive repair would be better in 1k it’s higher quality and don’t get sucked in by high heat paint it’s BS IMHO and I’m not alone
