Exhaust Paint

[jgbrown59]

Exhaust paint question. I'm working on a late 1948 FL and want to paint the exhaust as close to original as I can. In Palmer's third edition it mentions the exhaust pipes for 1932 to 48 were painted in a "special high-temperature black paint" (pg 869).

What paint are people using to get close to correct for this exhaust? From pictures this is a glossy finish.

I found this thread so at least its a start - using PJ1 or POR:

Rustoleum has an ultra high temperature gloss black that I’ve been using. It flattens out over time which gives it a more authentic look in my opinion. Maybe not the best option if you’re looking for your bike to remain newly restored forever.

I have very good results with these products.

Thanks to all of you for the information. I want the bike to start off correct but then age appropriately over time since I plan to ride it. I like the idea of the paint flattening over time as I assume that is what the factory exhaust paint did.

I use H-D Heat Resistant Silver (98660-78) for panhead cylinders (ordered from local H-D dealer). I tried searching online for 98606FL and couldn't find it but I did find this H-D Exhaust paint - 98606BAY.
This appears gloss per the lid. I'll see what the dealer has to say.

In the mean time I am ordering the PJ1 and Rust Oleum High Heat Ultra semi-gloss so I'll have some options.

Thanks for the assist - Happy Holidays / Merry Christmas to all!

most of the high temp paints recommend that you put the painted pieces in the oven to cure. That gives them a uniform color throughout the entire pieces. I'v always do this process twice, giving the headers, pipes and muffler resistant to scratches and normal wear for extended life. I like the PJ1 paint, not so much for the POR products. To each, his own.. spending time with the prep process makes for better results. Good Luck, C2K

Air cure Cerakote in black velvet is a great choice
