anyone painted hi temp paint over their ugly Harley gray powder coating? id like to have my nightster motor mostly black, i figured if I prep it like it was bare metal ( de greasing) the hi temp should stick right to it right?

I thought it was paint from the moco, not powder? I'm guessing it would stick. I got some carb cleaner on my motor, and the paint peeled right off! I bet you could spray it with aircraft paint remover and get it off pretty quickly. Just don't get that stuff on anything else...including your skin. I hear it's nasty stuff!

try using Berryman Chemtool gasket remover that stuff will blister and peel powdercoat without much effort.

The extent of your prep work, will determine the end result of your paint job.
When I painted my motor, I degreased it, with an industrial strength degreaser and water. After it dried, I went over any surfaces to be painted with a red scotch-brite pad to give the paint a good surface to adhere to. I then wiped down the areas to be painted with wax and grease remover. Masked everything off, wiped it down with wax and grease remover a second time and, then went ahead spraying it with VHT. The end result was exactly as I hoped a smooth and clean paint job. Just be sure to take into account any special procedures the paint requires as far as curing.

500* high temp spray paint worked great for me!
Powerwashed it clean let it dry and sprayed it. No problems in 500 miles.

I used Dupli Color flat black.. I didn't bake it yet but once done looks like it will be great!

My buddy painted his Dyna motor with some high temp spray paint from the parts store. I didn't think it would hold up, but he's been riding it for over a year without any changes. Like others have said, the prep work determines the end result.

Painted mine with VHT flat black. I think the paint adheres to the powder coat better than raw aluminum, acts like a primer.
