Prepping Frame for Painting

Starting the restoration of Weber Genesis Silver B this weekend and decided to do it right and repaint the Frame. I plan on grinding any rust and treating with VHT before painting, but couldn’t find a good guide on the best way to paint. I’m using the Rustoleum High Temp Ultra Paint.

Do I need to sand down the entire frame? Is primer necessary? How long to let the paint cure before re-assembly?

Thanks for any help!
 
Grind any rust, prime any bare metal and prep it with a good solvent. I use either rubbing alcohol or Xylol. Let it dry for an hour or so before painting and go for it. I use the Rusto High Heat ultra around the top where the cook box is, but I us the Rusto 2x gloss black everywhere else. You can use the high heat all over, but it is more expensive and not quite as shiny. No need to strip the whole frame...in fact, I don't recommend that.

What kind of primer do you use? Self etching?
 
I use Rustoleum Rust reformer in place of any kind of primer. It acts much like a primer but will help mitigate any small spots of rust that were missed. Also, the Rustoleum 2x paints and Ultra High Heat are designed to be applied directly to bare metal.

I recently used Eastwood internal frame coating rust converter outside the frame as a primer. Then painted over with the ultra high heat paint. After days of drying The paint and Eastwood easily rubbed and flaked off. Do you think this is because of the Eastwood stuff being used?

If the Eastwood wasn’t fully cured, the Rustoleum could have reactivated the solvents and messed up the cure.

If it was really humid that could have prevented the Eastwood from curing fully.

It was definitely very humid and I didn’t give it enough time to cure. I think I sprayed the topcoat on four hours after I sprayed the Eastwood. Is the Eastwood not as forgiving as a generic primer with application?
