Painting the trunks/engine bay/underside/cabin, POR-15 and leave black? Options

[boxsterfan]

I have been thinking about what I will do with my car in the future when it comes time to restore. On many cars, I see people have appeared to POR-15 (or other) the trunks/engine bay/underside/cabin and then left it black? They then go on to paint the rest of the car as normal (orange, red, white, green, etc...)

I'm not looking to build a concourse winner myself. I am looking to build a car that is restored and protected from rust for as long as possible (another 40 years lets say).

What do people think of POR-15'ing (or any other product) the trunks/engine bay/underside/cabin and then leaving those areas as that? And then (in my case blue) painting the rest of the car as normal?

I POR'd my fuel tank and have to say it seemed to do a great job.

But the other part of your question. My two trunks were pretty knocked around after nearly forty years of use. I wire brushed the entire area and rust treated and primed any areas that were suspect. In most places the original paint was good.

I found a metallic grey single pot paint that I rolled on. It leaves a hammer finish, looks really good and left a hard and serviceable finish. If you are interested I will put some phots up after work tonight and give you a description of the paint. Considering most of the area is covered with carpet or spare wheel etc it doesn't matter too much unless you are totally into originality.

I have heard the good and the bad stories, and I have used POR-15. What I have found is that if you FOLLOW THE INSTRUCTIONS to the letter, you will get great results. There is a post above, complaining about removing the rock hard POR-15. That is how it is supposed to work. I say try it, then you will know. I basically painted my whole car with the stuff. inside the gas tank too. Here are some shots:

my trunk after a patch job. the bubbles are either the "metal ready" or the "marine clean" working. This is my 1st time I welded in 30 years, so don't be critical. (IMG:style_emoticons/default/piratenanner.gif) I also used the POR patch as a seam sealer, also highly recommend that product.


POR patch is black.



I ruffed it up with a light sanding then painted over the seam sealer. It will look even better when the carpet is on top of it..... (IMG:style_emoticons/default/aktion035.gif)
