I admit I forgot to do a before any pic. But these 2 shots of the header pipe show the difference before the second coat and after. Just thought some might like to see how this stuff works. Brush it on, wait 5 minutes & rinse it off! The top pic is the whole pipe after. Victor

One more close up of the header after it dried. Victor

When you repaint this, I would highly suggest a ceramic high-heat paint. You will like it. It gives a nice satin sheen that is very durable. I saw a couple pipes painted with a ceramic high heat paint at HD a couple years ago and they were beautiful. I re-painted my Model 94 pipe and it remains black after two years.

Exactly what I like to use! Victor

Here’s a shot....

I use the Duplicolor Aluminum engine paint on cases and head. Pretty tough and gas resistant.

Yes! now isn't that the most beautiful pipe ya ever saw?!?! I think it's perfect because it's got just enough shine, but not too much either. And it stays black!

Yep! And it’s also great for the black cylinder too! Victor

Do you have to cook the painted item to set and cure the Duplicolor paint?

The instructions do not mention baking the paint and I don’t. In the cold weather I will set the piece in front of the heater in the shop for a couple of days though. I think the heat from the engine cooks it fairly well.
I have not used it on a pipe, but seeing the results now, I will give it a try.

I find the break in cycles heat the paint enough. I’ve done five pipes with it so far and they all got heated up during the break in cycling. And it’s held up really well! Victor

Cool Victor. That pipe looks great!! I've been using racing castor in some of my race bikes lately so those pipes get cooked every year. I'll try some.

I went to get some of that Dupli Color black paint today and found that the have it in Gloss, semi gloss and low gloss. Which one are you guys using?

I’ve always used the low gloss. It’s sort of like a satin finish, not matte or flat. Victor

Thanks Victor. I’ll give it a try.

Do you guys primer the exhaust before painting or just shoot it with paint after whatever rust removal process you use? And do you apply any type of clear?
Thanks.

Adam, for race bikes, I've been running Maxima 927 racing castor at 20:1 so the pipes get an annual cooking. After the cook, I lightly sand them, clean them with solvent, and spray them with flat black manifold paint. Once the paint is cured, I run the bike to get a good film of oil in the chamber before I put the bike up for the winter to inhibit rust formation. That holds up well for the next season. For street/trail bikes, I use Rustoleum high-temp grill paint made for rust inhibition. If a little rust shows through, I sand it off, lightly sand the rest of the pipe and respray it. I like the look of a nice, flat black pipe. No primer, no top coat.

I don’t even think they make a primer that’s high heat paint, do they? Victor

I guess evidently they do. Reckon I'll be the odd man out and give it a try lol

Wow! I’ve never seen that before! Let us know how it goes! Post pics when done! Victor

I’ll give it a try on my pipes soon. Although I might just try some muriatic acid, since I have some in the garage. I looked up the naval jelly and it’s phosphoric acid.
