What is the best cleaning solution to use when preparing metal to be painted with POR 15? I am taking out my radiator support and painting it. It has a little rust on it but not too bad.

Ed is right - I did the wire brush thing and used a degreaser - then used the metal ready. You have to rinse and dry afterward, before painting. But it does a good job.

I just did the radiator support off my 72 this week with POR15. I cleaned it with degreaser, dried it with air, used the Metal Ready in a small container with a brush, keep it wet for about 20 minutes then rinse it off with water, dry it with air, then I dry it again with a heat gun to get all the moisture out of the cracks,etc, then painted with the POR15 gloss black and let sit for a day to dry. I did one side per day. I have it finished now with one coat. I'm not using 2 coats for this but some parts I used 2 coats then a top coat. This takes a while but comes out nice.I figure the support will be covered and dry most of the time, so 1 coat should be ok.

Hope I'm not too late to the party...

Just so you know, you asked about cleaners- metal ready isn't going to degrease the part.

The recommended procedure is cleaning/degreasing with Marine Clean diluted with water. They say it works best when diluted and I can attest to that.

That is followed by the Metal Ready which converts rust and etches the surface. This provides "tooth" for the paint to adhere to.

Then POR-15 coats and top coat if necessary.

Whatever you do, do not use a petroleum distillate to degrease. It'll goof up the curing of the POR-15. That point isn't real prominent in the instructions...

Bingo! Metal Ready it is. It adds a coating of Zinc.
