I have bought a can of POR15 and will be starting on my frame soon. My question is how runny is this stuff at about 90 degrees and high humidity levels. My plan is to open can and pour out a small quantity using a can pour spout then place plastic wrap over can and reseal immediately. After sealing I will place in fridge. I plan to use a foam brush and a cherry picker to avoid laying on my back to paint.

VIP Question. Have any of you done a small portion and later added another section?

POR15 said to lightly sand till the gloss was gone in the overlap area. Any suggestions would be appreciated.

Also I have to leave a few areas undone for now (where the IFS will go) and was wondering about weld splatter on POR15. I was told to spray a non stick cooking spray on at that would stop 99% of weld splatter stick.

OK Last question for now. Did everyone use POR15's metal prep. They said it was very important to use this on sandblasted metal. Why can't I use another product that contains Phosphoric acid and is cheaper?

 

Hi Charles, haven't seen you in awhile.

>>My question is how runny is this stuff at about 90 degrees and high humidity levels.<<

I haven't had any problems using it in the heat and humidity (Fla. also). It's pretty thick stuff unless you use their thinner for using it in a spray gun.

>>My plan is to open can and pour out a small quantity using a can pour spout then place plastic wrap over can and reseal immediately.<<

When I've used just small amounts I would pour the POR into one of those throw away ZipLock bowls with a lid. If you don't use all the paint, you can put the lid on it, throw it in the fridge and it's good to go for the next time. Otherwise, just throw it out and no mess to clean up. One thing, you'll need to clean your pour spout before you start painting if you want to be able to get the paint out.

>>I plan to use a foam brush<<

Good choice. I personally prefer the ease of applying it with the foam over a bristle brush. Make sure you have spares handy.

All the time.

The only time I ever sanded it was when I put Icing on to fill some of the real pitted areas that were going to be visable

Sorry, I never tried that. Once the paint had been dry for a few weeks and it came time for Steve to do some welding, I'd just flick the weld splatter off (when they cooled of course).

I actually prefer Ospho. It's much cheaper, readily available at Home Depot and doesn't have to be washed off.

 

Thanks Carlene,

I really appreciate the thorough reply. I actually hoped you would reply I remember that you had used it before. I added a new group of pics to my gallery that shows the frame work. I like the idea of using Ospho and from what you are saying I am on target with the rest. Thanks for the Ziplock bowl/fridge tip. Very cool.

Question. When filling pits do you ever spray a high fill primer on while the POR15 is still tacky? I was told it would eliminate the need for the Tie Bond primer they sell and allow me to use Icing or any top coat.

Many thanks,
Charles in Pensacola FL (the opposite end from WPB)

PS Is anybody from Pensacola

 

Hey Charles - just me again.

We didn't have enough bad areas on our '41 frame to worry about (believe it or not). The frame is in great shape. I just scuffed the POR, used "Icing" to fill some pitted areas then painted more POR over it.

As for painting when tacky, here's an old thread that you were involved in quite some time ago.

More Stuff on POR-15

BTW - I like your photo gallery. I especially like that you took the extra time to tell about each photo. Nice job.

Almost forgot. Did you know that there's a Florida Chapter on FTE now. TheWiz set up a checkin thread so you may want to take a look and see if there's anyone from your area.
