POR-15 Engine Enamel

I've read almost all of the "engine paint" related threads on here, and there seems to be a misconception as far as POR-15 products. I've been looking for an ideal paint for my SBC and have heard to use an epoxy primer, as well as the POR-15 Engine Enamel (not the POR-15 rust treatment products..)


So, I took a trip to one of my local paint suppliers, asked about a decent Epoxy, and was asked what I'd be painting.. When I had mentioned that it'd be used on an engine, the salesguy immediately suggested POR-15 Engine Enamel (1k, no primer).. His concern was the same as one that I'd had reading posts; How well would a "plain ole" 2k Epoxy Primer/Basecoat/Clearcoat hold up to an engine's heat?

I had mentioned to him that I'd read that regular epoxy would hold up well, and that specialty paints weren't always necessary (he had mentioned an engine getting up to 1500, I had told him that maybe at the exhaust ports, the headers might be, but a block and heads shouldn't be even close to that..)


So, I ended up putting in an order for 2 pints of POR-15 Engine Enamel.. Should I have just picked up some Epoxy?? Any experienced input?? Please; no hearsay, I've been reading "friend of a friend" stories for the past couple of days..


Thanks for any input; it is greatly appreciated..

(BTW- the engine is a rebuilt SBC with less than 100 miles, going in a driver, not a show car.. I'd like it to hold up to a little fun on the street, as well as some test & tune fun, and after stripping the paint once, I'd rather never do it again unless rebuilding..)

BAH!, I originally painted the engine (respray, actually) with spraycan, I think I used Dupli-color.... the engine was painted when I bought it- but there were a few spots I went over.. It chipped, peeled, and looks

You can have good results with just about anything, as long as you do the right prep work. Cleaning and degreasing is a must, and with all the road grime and dust that can collect the pores of the block that is almost impossible with out sandblasting or hot tanking.

something else that works really well- if you like black is Rustoleum BBQ paint... yea sounds wierd, and it only comes in flat black, but I can attest that it can hold up to the heat. Plus flat black is good at masking any grease you get on the engine.

Which was one of my worries, the engine hasn't seen much time on the road... It is down to metal, and I cleaned it up with Acetone, but it's still assembled, so I'd like to avoid as much disassembly as possible.... I was thinking to brush on some Acetone and wipe to get the engine as clean as I can..

por-15

I've used por-15 engine enamel on two motors. My 68 camaro I painted 5 years ago and it still looks great.I just finished a 56 Chevy p/up and used it on the motor.It holds up great and can be applied with a brush if you don't want to spray. It flows very well.I also used their chassis paint.Sprayed that on. Your money was well spent. You can check out my pictures on this site. Good luck with your project...

I just painted my block & heads with POR 15 Chevy Orange engine enamel.Although I didnt use any special primer,there was a good base coat from my previous rebuild,I cleaned that really good,brake cleaner & wiped it down with laquer thinner.The brushed on POR 15 looks like it was sprayed on,and its already been warmed up on a dyno run.I've had lots of compliments on how good it looks.I bought a quart can and still have lots left over,and I did the water pump & bellhousing.

I painted my last engine with the POR-15 engine enamel. The engine was assembled. I took extra time with the degreasing. I masked well and used a brush. Turned out very well. Two years later I noticed a small amount of flaking around a spark plug hole which was touched up with the same product. I would use it again. The only downside I recall is that the manufacturer recommends a rather long dry / cure time. Post-painting oil weeps and such don't seem to affect, deteriorate, or weaken the finish.

I have been told by pros that most engines can be painted with the same paint as the body is painted with. Have never tried it but I see a lot of engines where the engine color matches the body color so it is perhaps reasonable to suggest the same paint has been used.

I brushed mine on when I used the POR 15 and after it dried overnight all of the brushmarks were gone. I would not spray it and whatever it gets on it stays on so wear gloves and put something on the floor in case you spill.
