I'm considering painting my engine chevy orange. I noticed that por-15 has a paint in that color for engines. Anyone used it? If so, I assume it was done using a brush?
yes i used the red eng paint on my frt end and gastank and engine block, u just brush it on and it leaves no brush strokes. it looks like powdercoating, i love this paint

I used it on my big block last summer. I brushed the block and sparyed the bolt on parts. (Valve covers, oil pan, timing cover etc). Both methods produce a nice finish, but I prefer using the gun.
One thing to watch is the color difference from one can to the next. Each can I opened was a slightly different color.
My results with POR 15 was very favorable, but I haven't used the engine paint. POR flows very nicely and doesn't show brush marks when applied as directed. It proved better than powder coat to me, as it is resistant to fuel and other hydrocarbons. For example, my control arms were powder coated gloss black. Thinking powder was resistant to chemicals, I tried wiping grime off the lower arms with lacquer thinner. Slowly, I noticed the black powder was coming off with the grime. That did not happen when I tried it on my black POR 15 painted frame. I must assume the engine paint is just as resistant to fuel and other harsh chemicals.
What are you guys using for primer?
POR15 is recommended to be applied over rusty metal without a primer but
I've heard about adhesion problems over clean metal without a primer.
If you spray do you need to thin it out, and if you do what do you use-paint thiner? THANKS JON
According to the POR-15 instructions you can thin the product 10% for spray applications but you must use the POR-15 reducer. I have sprayed it without reducer and it seems to work well. One the flip side, too much reducer will give you runs very easily. See my post on engine bay painting.

Primer is not recommended. Marine Clean, Metal Ready & shoot. If you are painting over an existing POR-15 finish, they sell a self etching primer, but its $30 for a spray bomb.
I have used POR-15 many times and I found the engine paint to be very durable. If you have a concern with slight shade differance in cans just mix the cans together for a uniform blem in color.
I would have to say that the posted examples above are some of the nicest I have seen. That BB looks way and I realy like the detail of the frame and suspension.
I sprayed the full undercariage of a '66 Buick Riviera and was very pleased with the results.
Make sure you ware protection when spraying; that stuff has to wear off is it get on your skin and I would hate to think what it could do to your lungs.

I agree, you can blend the cans together if you know there is a possibility of a mix match. I didn't notice the problem until I opened the second can. From now on, I'll be opening all the cans first.
