It is their Engine Enamel product. I would be very surprised if POR-15 represented a product for engine use that had not been tested. I have used their products on other applications on the car that are working extremely well. Some of the product has been in use over 6 years and it still looks as good as the day it was first applied.

I was more interested in when the best time was to do the painting. I've decided to paint before assembly so the bolts and accessories stand out more.

One more question. Should the surfaces where bolts occur on the exterior be masked off so bolts mate metal to metal or is a layer of paint between the bolt and the part an acceptable alternative. I'm thinking the surfaces probably should be masked off to assure metal to metal contact.

I wouldn't worry about a little paint between the bolt and the part...

I plan to use their engine enamel. I would be very suprized and disappointed if POR-15 would promote a product for engines that did not stand up to their claims. Like I said, I have used their other products on the frame and body with unquestionable success. I'm expecting the same from this product. I did check out the local auto supply stores and they have Dupli-Color high performance engine enamel and primer for a lot less than the POR-15 products. I want a quality, reliable and problem free finish that will look good for years to come. That's why I thought POR-15 would be the best.

Bottom line, I'm going with the POR-15 engine enamel and I'm going to mask the parts and paint them before assembly.

Thanks again for all your advice and ideas. Sure helps to have a good staff of people to call on.

The POR15 guy told me to use the black rust paint first and then top coat with the color. I brushed mine on within 24 hours so I wouldn't have to scuff the black.

Only issue I had was close to the center exhaust ports on the heads , the red discolored from the intense heat. 455 OLDS with siamesed exhaust ports in the center.
