I just got my sandblaster fired up and I'm ready to start getting various detail stuff cleaned and painted. What are your go-to coatings? I was thinking some high-temp rattle can paint for the brake drums, but I wasn't sure if some single stage black enamel from PPG would be just as good. Same question goes for painting the engine and exhaust manifolds, etc. What holds up the best? Maybe there's a thread already committed to this subject, but I didn't see one pop up after a quick search.
Things like brake drums don't normally require high temp paint, but given the reduced quality of regular rattle can paint these days, the high temp rattle can stuff may hold up better then the regular rattle can stuff does. The regular rattle can stuff available over the last few years (even the 2 in 1 Rustoleum with primer mixed in) the tends to need being resprayed in 3-5 years, but it too may work better with a primer under it. The modern auto body level single stage paint needs a good primer base. The real 2K epoxy really makes the paint stick to the metal.
I love this stuff. Easy to apply and re-apply without removing parts. I do my M/Cs, brake drums, exhaust manifolds, anything cast. A little goes a long way. Where gloves unless you want cast iron looking paws. I apply with a small rag or steel wool and wipe off excess with a blue paper towel.
The Appliance Paint from Rustoleum is good stuff, provides a thick, hard, coating that will last and will be fine on brake drums, intake manifolds, engine blocks, etc (not exhaust manifolds). Colors are limited. https://www.rustoleum.com/product-catalog/consumer-brands/specialty/appliance-epoxy
I've never had a problem with Rustoleum, even on calipers and rotors. If you think you need somthing more heat resistant, go with engine paint with MATCHING primer. I mention this, as the engine paint I've used was lacquer, and it makes an EVEL mess sprayed over enamel!
Hello, I bought a package from Duplicolor for a rusty surface brake drum. Since it gets hot, the matte black color coated the surface after some prep work. They looked great after finishing the paint. Once the wheels got put back in place, the work got hidden with the custom wheels, but I could see through the openings and the new black paint. The other choice was to used spray paint. But, in history, spray paint is not as thick or solid as brush on paint. But, of course, the choice is yours. The spray goes on easier and looks good. But, the coating is thin and leaves some doubt. YRMV Jnaki There are other brands that say heavy duty paint, so of course, the choice is yours. Dupli-Color Engine Enamel contains Ceramic Resins for maximum heat dissipation and gloss retention. The resins offer protection from exposure to excessive heat and automotive fluids. A neighbor used engine enamel as it was the only left over spray paint he had. He is/was happy with the results. So far, these are the only two used in a consistent manner. Duplicolor has a few colors that can be used for metals (disc brake/drum brake housings, etc.) that get warm or hot.
I used Rustoleum on the calipers and drums on the coupe and my daily driver pick up. over three years now still looks like the day I painted them.
I'm a Krylon user. The old stuff is harder to find and the "Fusion" **** seems to take longer to dry than I'm used to. Still faster than anything else I've used. Rattle can success and durability is directly related to cleanliness.
I use rustoleum high heat rattle can barbecue paint on exhaust. The manifolds and pipes on my roadster have almost 5k miles and look like new. It is a very flat paint. Only touch up I did was when I got oil on a header. John
I agree. I use the rustolium high temp barbecue paint on manifolds, and it still looks good after a couple years.
That stuff sounds like the stove polish they used to sell in the old days for use on wood burning pot belly stoves. It may still be available, I don't know. Eastwood used to sell a stainless steel paint that worked well on exhaust manifolds, again I don't know if it's still available but you could check their website. I use regular old spray paint from Rustoleum or Krylon on brake drums, I don't think in normal driving they get that hot unless maybe you're in compe***ion or going down mountain roads. For the engine, it can depend on what make engine you're using. For example, Pontiacs are famous for burning the paint off the center exhaust ports on the cylinder heads. I've had some luck with putting a thin coat of high temp aluminum color paint on those areas before applying the color coat, but eventually they'll burn off no matter what is used.
I use this on manifolds, haven't seen it burn off yet after years of use. https://forrestpaint.com/product/st...consumer/stove-bright-high-temperature-paint/
All this talk about rattle can paint. I thought catalyzed urethane paint is what's always recommended for basically everything except exhaust. Johnny seems open to using it. Hot Stuff and stove paint work well for exhaust manifolds. But I think Cerakote Glacier series has the best heat and chemical resistance of all.
Yep, I'm open to whatever works best. I have stuff I need to paint with urethane anyway. If there was something better for heat that was a rattle can that I can spray in the driveway, that's a bonus, just because it's so much work to put up plastic for a temporary spray booth and whatnot.
I used that stuff maybe 20 years ago and it looked great!! But as soon as it got wet it washed the stuff off. Hopefully it's gotten better since then. It sure looked nice once it was applied! Larry
OK Billy, so how do you "burn it on" just run the engine up to temp for awhile? If so the stuff looks like it has a good look to it..
I painted the stock cast iron manifolds with Eastwood brush on high heat. 13 yrs and still ok like they did then .
VHT for the manifolds and if they fit put them in the oven at say 400 degrees for 45 minutes. Brake drums I sandblast and coat with epoxy primer then it doesn’t matter what paint is used on top.
Any updates on the Plymouth project? Or have I missed them? Most entertaining build thread on the HAMB.
I've made a fair amount of progress, nothing that's really too interesting. Just haven't been motivated enough to post.
My go to is Rustoleum hammertone Spray can paints for all ch***is and brake drums. No primer required, and it’s plenty durable. No mixing, spray guns to clean etc.
