Best way to prep trailer for paint.

[RaisedByWolves]

I used a wire cup brush on a 4" grinder and a similar wheel on some air tools, then brushed on a base coat of Rustoleium rusty metal primer.

I finished it with silver hammertone paint as my frame had pitting and this helped hide it.

I have had equipment painted with nothing but the rustolieum RMP and it held up for over 10yrs with no top coat of paint.

Good stuff!

Sorry for never updating this thread.

The dustless blasting worked well for about 10 minutes. Then my big pressure washer took a crap. Trying to use it on my smaller washer was a waste of time.

I ended up just getting after it with a knotted cup brush and grinder, and using a cheap siphon feed air blaster for the nooks and crannies I couldn't reach.

I sprayed Rustoleum clean metal primer, and then gloss black with a HVLP gun. It came out really nice and seems to be holding up well.
