Good point, don't drink it. Rough it up with 80 grit try to get it back to bare metal ,use a acid etch. and,put down two coats of the silver then put black if you choose over that.That is a textbook application And don't forget to wear gloves.

Or, eliminate the Por-15 and use a good quality Epoxy Primer....better corrosion resistance, easier to apply and less chance of adhesion issues down the road.

I hear some of these stories about POR peeling off in sheets, I don't get it. I have used the stuff for years and never had a problem with adhesion. Of course I always follow the directions. Not saying the other people did not, maybe some of these were a bad batch?

Go to POR 15 website ,I used it on my truck no problems ,*** is not as smooth as I would have liked ,I scuffed my frame with 36 grit Before I received paint and instructions ,There sight says Do Not sand or it will not stick prone to Peel ,on the sight it says you brush it or spray it ,I brushed mine if I could do it again I would spray it . I will try to post a picture.

I've used Por-15 and had great results...took a set of new headers, sandblasted them, let them sit and oxidize for a few days and applied Por-15...12 years later, the headers are still black and look good. I also had a customer of mine apply Por-15 on the inside of a pair of fenders...it literally fell off. I agree with Sedanbob, if you follow the instructions, chances are it will work...that being said, if a product is that susceptible to not adhering (and there have been numerous threads on this very subject...and I have yet to see a thread about Epoxy primer not sticking)and a quality Epoxy Primer will stick like poop on a blanket...why chance using NOT using a quality Epoxy Primer?

Once opened it has a short shelf life ,don't try to save it for next job ,,I bought a gallon only needed a quart.so I gave remainder to a friend to use on his project,,it helps some to put a sheet of shrink wrap under lid before sealing it ,,much easier to get lid off next time you use it ,,which probably every one already knew that.

Exactly why I buy it in quarts amd use a "turkey baster" to get it out of the can so I do not get in the grooves on top of the can.

never thought about that,,i have ben using 2 in tape half way around can to make a pour spout ,dont spill on side of can to cover writing makes pouring easy ,when finished take off tape throw it away you are clean ,,
also a tip I drill a 1/8 hole in the lip of the can so it can drain back in can it will still seal good ,the plastic is just insurance and ease lid removal.

guess who wrote the application guide for that product in 1987. Someday I will try to explain the technology behind the coating That generic type of coating when manufactured correctly and used directly as one of the most powerful systems available Most bridges that use this type of system can go as long as 25 years without a repaint I don't feel like starting any type controversy. Besides, my mothers calling me
