I was wondering what the effects are if you use rattle can paint on an engine block, will it hold up? I can't find the color I want in high temp engine paint
Not necessary to use hi-temp engine paint...Use a urethane...it'll hold up...I've painted several with single stage urethane...just make sure to clean the block well before spraying and put down a base of epoxy . R-
Holy ****, has anyone seen the One Shot Enamel paint that GMC BUBBA used? It was pretty stunning! Here's the thread... http://www.jalopyjournal.com/forum/showthread.php?t=473149 40StudeDude, why is it necessary to use Urethane?
I used to rattle can Chevy's with great results. Any engine with the exhaust ports extending beyond the head like Studebaker, Pontiac and Oldsmobile will burn off the paint just like it would on the headers or Ex manifolds but the rest of the engine will hold up just fine. I don't think that anything will withstand those temps. If I see a Pontiac with pristine paint on the heads at the manifold connection, I know that it is either a fresh car or a trailer queen. I don't see that "hi temp" paint is required. I use automotive paint for all my engines.
It's NOT NECESSARY to use urethane, I never stated that...don't put words into my reply. I simply said to use urethane simply becuz it holds up...and doesn't flake off after it's been on the engine a while (like YEARS)...I painted my rad '57 Chevy's engine in urethane in 1990 (Mint green BTW, a very light color)...it still looks as good as the day I put it on and it's easy to clean and keep clean...and that's over 60,000 miles ago.

yeah you will be fine..and Hey Bubba..get a resperator on! yer making us all look bad..****ing all those paint fumes maybe not the best picture, but this is regular automotive paint 68 Firebird one year color
Whoa settle down there! I was asking because I know nothing about painting and was wondering if there was some insight into urethane. I see one guy using Enamel and another using Urethane. I just wanted to know the pros and cons in your opinion. Geesh....
I have used straight single stage acrylic enamel with excellent results......there's not all that much heat in the block such that it would peel the enamel.......it stays glossy too! CB
hahaha yeah but he looks like he has been holding his breath too long and that nice orange cloud in front of him...yummy im just messin with him..its his lungs after all
The main thing for good paint adhesion/results is to make sure you have it degreased really well... can't stress that enough. Even when you think you've done all you can... degrease it again! Then use a good primer and top coat.
Paints that work: Urethane, single stage, and base/clear Acrylic enamel, with the hardener (better chemical resistance) Imron (polyurethane enamel) Even HOK candies and pearls, as long as you use the urethane clear.
I painted my 283 with tractor paint from Tractor Supply. It's International Harvester red. Valspar brand. Mixed it 3 to 1 with acetone and poured a cap full of hardener in with it. Turned out great!
Not Rattle can paint but its not bad. Went down to the local Dupont store and bought one of those arasol spay kits where you mix the paint and screw the gl*** jar full of paint onto it. Talked to the guy there about what I was doing and he gave me a small half pint of color, a small can of reducer and the mixing cup for free. What do ya think???? I like it because it has a better shine than the rattle can and is SOOO much easier to wipe grease and oil off of!! Yes it is John Deere Green!! Has been for fifty some years!!
Painted mine with acrylic enamel 30 years ago. Brushed it on, flows right out. Still shiny. Just touched it up a few months ago. pics are then and now
POR-15 top coat, that ***uming you like a black motor. Goes on like an old enamel, covers and "sticks" great. It has looked great for three years:
