Thread: Painting engine

Tweet

I am going to paint my 62 Corvette the original red using PPG paint. I plan tp paint the car, under hood and chassic the same color with the same paint.
I would like to paint the engine with the same paint, will it stay on or do you have to mix anything special to make it high temp paint.
Thanks,
Wade

You need high temp paint. I remember seeing on the show "Trucks" Stacey using PPG paint to paint the engine but it wasn't regular paint, it had the same paint code but if I remember correctly it was for high temp. If not then it will bubble and flake off. We just got a Vette back in the shop where the hood bubbled because the guy is trying to run a 11.5:1 comp ratio engine on the street as a daily driver and it's overheating so in turn is getting that fiberglass hood scortching hot. So if the hood is doing this then so will the block of course. PPG should be able to color match it for you and get high temp. I like a car where the engine compartment and engine are painted the same as the car. Should look very good when your done!

the reason the paint was bubbling on the hood is because it wasnt prepped correctly during the first paint job, fiberglass constantly gasses and if you apply heat, it does this at a faster rate. there wasnt a good enough barrier between the 'glass and the paint.

we painted a 427 with HOK paint, with no additives. clean block very well, prime with epoxy primer, base with orion silver, mid-coat with candy apple, and clear....best looking engine i have seen i think.

If anyone tells you that engines have to have hi temp paint they are wrong. I have painted many engines with epoxy primer and various top coats, they hold up great. (17 years on my '27, still shines bright red)

This is how all the pro shops paint them.

i agree! it has to be clean.

Oh your in South Carolina, I just noticed that... How far are you from Fort Mill or Rock Hill?

Hellraiser, I am about 50 miles from Rock Hill, there are 2 Elgins in SC, one is in Lancaster county and one is in Kershaw county, I am in Kershaw county, near Camden if you know where that is, have you ever been here?
Thanks also for your reply, thats what I thought.
Do you own a body shop?
Thanks again,

i'm not saying fmx is wrong, you cant go wrong there, but look at my pic. and the white el camino with the white motor is the same paint i painted the car with. i painted over red and it was driven daily, the blower turned pink in about 2 yrs. the blower gets awhole lot hotter than the motor. the red conv. motor is reg. paint all so.

i have painted many more than a dozen engines with enamel with harder and two part urethane. never had any bad thing stop me from using it again . hi mike

I know a lot of people that paint engines with regular non hi temp paint. I'm going to use hi temp Dupli Color black paint on my 200 I6 when that time comes, just because we don't meet OSHA regulations for spraying paint with a sprayer. I'm also going to shoot a coat of the hi temp high gloss clear too.

I've used DP primer and base coat clear coat, single stage, and even Imron on engines... If the surface is prepped properly it stays on fairly well. I hate the limited color selection in the rattle can hi temps and have had real good luck with it staying on....

my friend made cast valve covers i have used many gallons of PPG dp90 and dau75 clear on cast alum and mag on the cast covers and rims he made

When you guys used red, did it not turn to a pinkish or orange? Anyways, I live in NC but RIGHT near Lancaster. I work at a hot rod shop up here next to Carowinds (Carowinds exit in Fort Mill).

51Deluxe, you could probably be right. I don't know how it was prepped or painted since I didn't do it and it was done before I ever worked there. When the guy brought the car in though, the hood was BURNING hot to where you couldn't barely touch it without burning yourself. I figured that since it got so hot that it reacted underneath the paint and since it's fiberglass and not metal, it made it bubble like that.

Here is my experience.

I've used two part urethane paints on engines without a single problem.

The only reds I've ever had turn pink or orange are "cheap paint". Quality paint won't fade that badly....and I live in the ultraviolet capital of the world! :-0

When was the last time you saw bubbled paint on the hood of a Corvette?.....probably never? The problem is in the paint application. One of several possibilities is that they used lacquer spot putty, which will blister under a urethane paint.
