POR 15 left Air Bubbles! Why?

[poopdevil]

WTF!
I used Por 15 on my clutch assembly while rebuilding it last night and this morning there are alot of tiny pindots on it .
Looks like air bubbles.
Anyone else have this problem?
I did shake the can to mix it. Is this why?
I didnt know you couldnt do that.
Just asking.
I am totally irritated with it.
What a bummer.

WTF is your problem man. Geez. I never said I was irritated with the product. I didn't go online first and I figured it was my doing. I just wanted to make sure that was the reason.
I was stating I was irritated at the situation. the (it ) meaning the outcome.
Go bash someone offline.
It's easy to be a jerk to people in a forum setting.
I was just asking around to confirm my own mistake.

[poopdevil]

By the way, does anyone know if the Por is ruined now or will it go back to normal with time?

[Chris Hollaway]

It will probably settle after a few days or so. Also, what you don't use in the can, put some wax paper or plastic between the lid and can. You can put it in the frig to extend the shelf life. I put the whole can in a big ziploc bag.

[Chris Hollaway]

Just to make you feel better, I did the samething. Just habit I guess.

[poopdevil]

Thanks man, Nice to hear a positive response.
Was habit for me too.
I do know of the baggy thing. I learned that the hard way a can or 2 ago..
hehe

The bubbles could be from oil or something left on the metal.

Wrong WRONG WRONG

well.. most likely.


It makes bubbles if it is on with any sort of thickness at all. It captures escaping gas. It films over instantly and any gasses in the paint due to excessive thickness will get stuck and cause bubbles to form. It wants to go on in two .. VERY thin coverings and you must wait till you get that "slight finger drag" I figure that means a bit closer to dry than tacky.
You MUST put down a second coat as even the thin coat has tiny little bubble holes in it. That's why it says (on all these products) 2 coats mandatory. And those bubbly puddle spots are hell to sand.. try to avoid them. This may be exacerbated by shaking the can.. but I only ever get bubbles where it pools.

If you ever doubt it will "foam up" when thick and cause bubbles.. leave that last little bit in the can.. just like an 1/8". Leave the lid off for 2 days. It'll puff up to about 3/8" inch and be spongy when cured.

I just did the inside of all my fenders and hood. Shook the can before hand. I've used por dozens of times .. always shake it. It smoothes out beautifully when put down thin. I mean.. you can top coat the stuff if you put it on with a roller and top coat it while still tacky. I don't even trust the "tie-coat" anymore. Guy at the paint shop said even the POR rep told em.. coat while tacky to get adhesion. I put it on with a foam roller.. nice and thin.. it looks like it was sprayed with a much better gun than mine.

Why were you putting por 15 on your clutch assy anyway?

[poopdevil]

I put it on because it was kinda rusty and chipped so I grinded it down and decided to use it instead of just paint because it is a nice hard finish and looks great.
I used marine clean first too so it had no oil etc. Might have been too thick a coat too.
I got it all off again and will give it another go tonight. Thanks for all the feedback

[zozo]

I did it too. Shake, shake, shake. That's life. Mr Perfect needs some sensitivity training on how not to be an asshole.

[Bugshift]

I was trained by a POR 15 rep. (we use alot of the stuff at the shop) They told us two thin coats. I got little bubbles once when I was in a hurry and did one thick coat.

Almost agree with all of the above, coupled with the fact that you're in Seattle, painting with a product that cures faster with high humidity. No time for it to lay out as smooth.

is it a moisture cure product?

I never payed attention, but I thought it was solvent...
regardless..
Seattle is a desert.. I live in hawaii and it smoothes out just fine.

Yep, directions, when read , even tell you not to sweat on it.

And there's a reason why Seattelites get the nickname "Web Foot".
