Cylinder and Head fins BLACK
Hey, my first post. Just bought a 2023 Ultra Limited that the dealer had tin swapped to Red-Line Red with blacked out motor. I fell in love a first glance.. lol
I've ordered a complete set of Devil's Head Choppers magnetic bolt covers and a black side-stand. What will stick out most will be the cylinder and head fins... I searched the Google-web and found some very old discussions on painting just the edges. I'm considering using Cerakote and hand painting the edges. I'm a pretty patient guy. I've read that Cerakote can withstand 1800 degrees so temp not an issue. It'd be kinda like pin-stripping the motor lol...
I really don't want to tear down a new engine to black it out...
Thoughts please?
Thanks

Never had much luck with air-dry cerakote. Oven cured is usually best for durability and adhesion. Surfaces need to be extremely clean and prep'd properly which usually requires baking the oils out. For the guns I do, it's sonic cleaning with prep solvent then baking, I do this 3 times then apply the coating.
I can't imagine the prep time needed just to do one head, especially in the bike. Maybe on a bench, but even then, yowsa.

If it doesn't work, I can always try 80 grit to remove the paint. I'm not familiar with Cerakote use so am researching it.

The curing is now backwards how it should be which will lead to adhesion issues. Paints, cerakotes, etc are cured from the outside in, the slower curing on the inside is what promotes the adhesion to the surface. Having the engine hot would cure inside out. Your bike, you do you tho. Good luck with it.

Thanks for your input.
I would only warm motor to whatever, external, temperature ( I'll use a digital temp gun.), Cerakote recommends. I'm going to contact the company with my questions. I'll post response here when I get it.
If I can't do this, then down the road I'll look for a big bore kit that provides all black cylinders and heads..lol $$$

Shame my original question has degraded into some, somewhat, childish banter.
So, Cerakote told me NOT to use a brush. Thanks to all the adult responses.
Ciao

sometimes the truth hurts
i do a lot of metal work and finishing
there is NO short cut
when it comes to heat set finishes, control is of primary concern, i do not see it happening, but your dollar, your sweat and your tear
march on my brother, march on.
