POR 15 rust sealer

[bull]

I heard you cannot effectively paint over POR 15. Is that true?

[Silver R/T]

Not true, just scotch brite it real good, epoxy seal and you can paint over it

Here is another option.

If you don't use the tye coat. Your going to have to use a bit more then a scotch brite pad. POR is very hard use at least 180 wet or 100 dry. Get the gloss compleatly off to a uniform dull look before spraying over it with your filler primer. Do the same if your going to use filler putty instead.

POR-15 now makes a Self Etching Primer that's designed to go directly over CURED POR-15 WITHOUT sanding! They state there's no adhesion problems.
I'm doing the underside of my car this way. It's already been coated with black POR-15.

Drop Top,
Have you used the POR 15 primers?  Do they work as claimed?
I am going to use POR 15 and their primers, I just want to see who's been there and done that.

Sorry I have never used POR-15 primers. The POR-15 is a very good product. I don't use it very often. But when I have It has done everything it says it will do. I usually us i in places that you can't get to. A Speed/Custom shop here in town sells POR products and keeps it on the shelf and I've had a chance to have a close look at most of their products. Alot of the products that POR sells can be bought buy other companys for much less. However I haven't even looked into their primers ( i have my way of doing things & if it works don't fix it). But I do like the idea of their new primer that is designed to go over cured POR-15. I may have to try that some time in the future. I could have used that product a few years ago.
