Preping New bumper for Raptor

I Just got my JCR front bumper and I am wanting to spray it with "U-Pol Raptor" spray on bed liner. My question is, should I primer this first or just clean it up and spray the bumper bare metal?

I would spray primer if its in the white.

The raptor liner is fine to spray on bare metal, just make sure it's absolutely positively 100% clean, wax, and grease free. Wash it down with some water/dawn dish soap. Dry. Repeat 3 or 4 times.

Then right before you spray, wipe it down again with some 90% iso alcohol on a microfiber towel.

If you want to primer it, use a 2k epoxy primer (it's bare metal...), and MAKE SURE it's not anything spray bomb. Any lacquer based paints will lift rift off when the catalyzed raptor liner hits it.

Eastwood (re-branded Kirker) makes a cheap and decent epoxy primer. I got some for like $30 a quart to my door. I'm sure you'll find plenty of uses for it too...

if you want it to last spray primer on there before hand
