Por-15 usage ?
I have gotten myself some Por-15 for use on chassis work for my car. I wondered if I can apply it as normal paint . I thought that I read some where on the forum that you cannot use out of the can as normal paint. Do I have to separate the quantity for the job at hand from the bulk of the paint in the can and then discard any paint not used from that separated amount? Or can the unused amount be returned to the original amount in the can? thanx Brent

Seperate the portion you will be using...then discard any unused paint from that container. POR says it's contaminated and should not be returned to the original can. I even tried to seal the unused portion, but within a few hours it was hard.

Yeah, once it's been exposed to the air for a certain period of time, that's it, it can't be saved. Get yourself a little scoop (I found the ones used for mixing up iced tea are a good size) and use that to dish out the amount you'll need for the job. Don't plan on reusing the brush either, just get disposable ones and chuck them when you're done. Seal the can immediately after scooping out the prescribed amount. Put plastic wrap between the metal lid and the can to help seal it, and I've heard of people going so far as to put the can in a zip-lock bag and using a vacuum cleaner to suck out as much air as possible. Wear protection on your hands or plan on wearing the paint on your skin for a week. And don't use it in places exposed to sun -- I've seen the paint discolor and it may even break down.

Here's what you do....
1. Take the can punch a couple of holes on opposite sides of the top of the can for screws.
2. Pour only what you need into some sort of container and use it.
3. RIGHT AFTER you pour out what you need take the screws and screw them into the holes you punched into the top.
4. Take the can and turn it upside down so that the por-15 forms a seal and hardens around the screws.
5. When you want to use it again, remove the screws and repeat process.
My friend's Por-15 has held up for 7 months so far using this method. Hope it helps!! I plan on using this info this weekend.

I think it depends on the weather. I see your a neighbor to the north. I just paint the rear of my frame and didn't have any trouble. The first time was in December...sunny day, but cold. I brushed out of the can and when finished I put the lid in a zip lock sandwich bag and resealed. Second time last weekend. Opened can with no problem. Painted frame out of the can...took about 1.5 hours with can open and frequent stirring...resealed with lid in baggie. I think it was easier due the cold weather with no humidity. I painted my gas tank support too. I got everything cleaned up and then set out the steam vaporizer we use when the kids are sick. POR15 cures with humidity so the steam worked wonders. 10 hours later, frame and support dry to the touch. Reco...don't expect to use too much. I can't believe how little I used. I bought two quarts and I'll probably have enough left to do the 95 suburban frame!

Mason jars work well too
I had some Mason jars hanging around the basement...glass with the metal lid. Poured the contents of the can directly in to a mason jar and used a plastic bag between the lid and jar. That has been my storage for about 6 months... so far no hardening at all. I only open it long enough to pour some in to a small cup for painting.
I did some old rusty jack stands (just surface rust) with the leftover stuff... heck i didn't even really clean them up. AMAZING... look great and the paint is tough as nails. It took longer to dry than I thought, but no more than a day.
Wish it didn't smell so bad.... the smell is just icing on the cake of stripping rust off your frame laying on your back! I need a full body suit next time I work on the vette man.....

Search POR-15 and read their info on their home page. Most POR-15 paints are vulnerable to ultra-violet radiation. I think they say that only their black paint can withstand ultra violet. Using black on the frame should be fine, expecially since it doesn't get any direct ultra-violet. I'm using their grey color on a lot of places and I overspray it with Ford New Grey (The Ford grey motor color). They sell a lot of other interesting paint.
Fascinating that water vapor makes this stuff get hard and it's sensitive to ultra-violet. I think I'm going to try some of their clear to use over my chrome plated aluminum parts. ( They also make a two part clear paint for chrome.) These are chrome plated aluminum parts will get you into serious financial problems if they deteriorate and you need to replate them. The 69 factory sidepipe covers are chrome plated aluminum, along with the grills, etc on my 1970. Also I have chrome plated aluminum wheels.

Just did most of my rear suspension parts the other night. Great stuff and we have had a quart for about 4 yrs. It goes farther than you would think as we have about 1/3 of a quart left and have done the full suspension under my dads 57 and numerous other parts. We used the screw technique to seal the can and as I said...its lasted this long!
