ok, i got one coat on my fresh pans,frame last summer. first time i used the stuff. ran out of time had to leave and returned a week later. i want a second coat on bottom. got all the por 15 prep products. how would you all prep and apply? waiting for winter to pass. still just pans/frame. easy to flip over.

I'd prolly just blow it off w/air and wipe w/towel?

I would get rid of the dust, rescuff everything with a scotchbrite, then I would clean everything well with a wax and greese remover.
You could probably contact your salesman for his best suggestion.

i thooght a scuffing and cleaning with something(marine clean ) would be the route to go. its all new to me. i'll contact the por people for sure.

T8kitease, howd it turn out?. is it glossy,semi,or dull and cured like its supposed to? you just wet sanded with 600 wiped it clean and painted? no cleaner? sounds good.

Mark, Yep after the sanding just wiped it off and blew it off with the air compressor. Just make sure your temp is above 50 degrees, and humidity below 80%. I had to keep the garage warm with a portable heater. The finish is like a mirror, and as of now is rock solid. I did get some pin hole bubbles in the first coat here and there. But still looks great n will be covered by undercoating and carpet. Hope this helps.

POR-15 has to have a rough, clean surface to stick really well. It goes on thick and flows out well so think about using 220 grit sandpaper to scuff it up.

You might give this a try:

Quote: In response to many customer inquiries requesting a quick drying and easy-to-apply coating which enables a restorer to quickly topcoat POR-15® and other basecoats, we have developed POR-15® Self-Etching Primer.
With this product, you can even topcoat POR-15® that?s been in place for months or years.

POR-15® Self-Etching Primer is NOT a high-build primer, like POR-15?s TIECOAT PRIMER, but it can be sprayed or brushed on almost any painted surface and can be topcoated in 15 - 30 minutes. It bonds incredibly well to POR-15® Rust Preventive Paint, and all topcoats bond incredibly well to POR-15® Self-Etching Primer. It can be sanded lightly, and, if desired, multiple coats may be applied.

We strongly recommend this fine product, which we sell with our unconditional money-back guarantee of satisfaction. It is available in pints, quarts, and gallons as well as a large aerosol spray (15 ounces). In situations where you are topcoating a very old POR-15® finish, we first recommend a light sanding with any 280 to 320 grit paper.
