: POR-15 Engine Enamel - Drying Time?

I called POR-15 today and the guy told me that the engine enamel cures by the heat of the engine. If this is the case, how is this stuff going to dry as I won't be starting the engine for quite some time?

John. I have used VHT exhaust manifold paint as well as a different brand for the brake calipers. I guess both types are like POR engine paint. You should use the paint in many thin layers and they need heat to cure. Without heat it stays "soft" (not sticky) for a couple of days up to a week.
With a paint heat gun blowing through the inside of the exhaust manifold I have had it cured. If your engine block is still "open" you could try this heat gun method. Hope this helps.

I repaintd my motor in my 4 speed car(with the exception of the oilpan) with POR-15 engine paint last year with the motor in the car.The directions on the can specifically say let it sit for 3 days before starting it(I know someone that didn't wait..the painted bubbled).
Great stuff,pretty durable,and a year later,looks good still.

Hey John, Chris is right about letting the POR-15 cure for 3 days. I used it on my 67 Chevelle last year when I had the motor out. The motor still looks as good as the day I put it on. I'm sorry I don't have a picture for you to see. Good luck with your car.

I recently painted my new 327 with the POR-15 engine painting kit. I found that this system works really well on cast parts, such as the engine block, heads, intake, etc., producing a very nice high gloss finish. However, I wasn't satisfied with the way the paint looked on the smooth sheet metal surfaces of the valve covers, timing cover and oil pan. It dried with a lot of runs and brush strokes showing... After a bit of experimentation, I ended up stripping and repainting the sheet metal pieces with Duplicolor Ceramic Chevrolet orange/red engine paint. This is a near exact match for the POR-15 Chevrolet Orange paint. If you want to try this, be sure to get the Duplicolor "Chevrolet Orange-Red" paint and not the "Chevrolet Orange"; they actually offer both colors. Also, be sure to plan a full day for using the POR kit as there are several steps to do the job properly. As far a curing time, it did take almost a week before the surface was no longer tacky to the touch.
