edekalil Posted February 18, 2018 Report Share Posted February 18, 2018 Wondering what and how to coat a cast 510 exhaust to clean up the rusted look. Quote Link to comment
datzenmike Posted February 18, 2018 Report Share Posted February 18, 2018 I think there are 'do it yourself' ceramic coatings.... Then there's high heat paints. 1 Quote Link to comment
Ratwagon1600 Posted February 18, 2018 Report Share Posted February 18, 2018 If you can get access to a bead or sand blaster that’s a good start if you want to maintain the “naked look”. I’ve wrapped a set of headers previously with good results with a product similar to this. https://www.koolwrap.com.au/product-category/exhaust-wrap/ VHT do some rattle pack options which I have used before, again with good results. http://www.vhtpaint.com/high-heat/vht-flameproof-coating Quick edit. If you go the rattle pack option make sure you adhere to the manufacturers recommendations for drying/curing the paint or it won’t last for long. 1 Quote Link to comment
Stoffregen Motorsports Posted February 18, 2018 Report Share Posted February 18, 2018 Anti sieze can be used as a coating, and it looks very nice when it's burned on, but the burning on process is soooo toxic. I have done it this way before but because of the toxicity, I will never do it again. I like breathing... 3 Quote Link to comment
difrangia Posted February 18, 2018 Report Share Posted February 18, 2018 Jet-Hot does the high-temp alumina-ceramic that Mike mentioned. I've utilized their services a number of times over the past twenty five years and had several hundred dollars worth put on the little E1 in our 320 pickup when I re-did it. Locations in Oklahoma City and North Carolina and maybe other areas. I'd bet that there are other vendors who can shoot and bake the stuff on. https://www.jet-hot.com/ Quote Link to comment
G-Duax Posted February 18, 2018 Report Share Posted February 18, 2018 You never want to bead blast anything that is to be coated. Blasting with glass bead, or even fine steel shot will close the pores in the material, and coatings won't hold. Always use abrasive blasting, like aluminum oxide, as it helps open the pores, and allow coatings to adhere. Like Stoffregen says, other things work well, even better than rattle can products like VHT. I've used antisieze, and you have your choice of copper or stainless steel. Fumes ? Nothing compared with what I breathed while racing karts on open fuel, with who knows what in the mix. Just try holding your breath for a couple of formation laps. By the time they were ready to wave the green flag, anyone not on the front row couldn't see, let alone breath...... I've even used a graphite spray lube that held up longer than VHT. But for a really nice finish, just send it to someone who does the ceramic coat. Quote Link to comment
Dolomite Posted February 18, 2018 Report Share Posted February 18, 2018 Anti sieze can be used as a coating, and it looks very nice when it's burned on, but the burning on process is soooo toxic. I have done it this way before but because of the toxicity, I will never do it again. I like breathing... I just blocked my throttle to about 2k rpm and let it sit in the driveway for a few min, let cool and repeat a couple times. Then I wore a 3m mask and abused it up and down the block a couple times and she was good to go. Quote Link to comment
Draker Posted February 18, 2018 Report Share Posted February 18, 2018 I used VHT before, still holding up pretty nice. Quote Link to comment
Ratwagon1600 Posted February 18, 2018 Report Share Posted February 18, 2018 You never want to bead blast anything that is to be coated. Agreed. If you look at my post I suggested bead blasting if you want to “maintain the naked look” i.e. uncoated. Quote Link to comment
bananahamuck Posted February 18, 2018 Report Share Posted February 18, 2018 If i remember correctly someone on here cleaned manifold and then sprayed copper coating paint of some kind on it,, and heated it in and it looked very nice... Build threads are so hard to research by original poster anymore ,, so can't help any more than that. I am going to say it was Skib but ,,, memory fades. 1 Quote Link to comment
shacks510 Posted February 19, 2018 Report Share Posted February 19, 2018 I have VHT paint on my manifold, and it started to fall apart within a thousand miles or so. Anti sieze can be used as a coating, and it looks very nice when it's burned on, but the burning on process is soooo toxic. I have done it this way before but because of the toxicity, I will never do it again. I like breathing... I have seen this, and it’s something I’d like to try. I think it’s something you’d do on an already running/tuned engine, not a first start where you’re working over the engine adjusting things. Start the car and walk away deal. 1 Quote Link to comment
G-Duax Posted February 19, 2018 Report Share Posted February 19, 2018 JC Whitney used to have a silver, brush-on ceramic coating, that was cheap. I tried in on my old 521, and it worked well for many years, and was still staying put when I finally bailed on that old, abused wreck. Quote Link to comment

hang_510 Posted February 21, 2018 Report Share Posted February 21, 2018 I used some stove black stuff for cast iron. Still kinda black after 25,000 mi. Quote Link to comment
