POR 15

Postby mazzo » Sat Aug 27, 2022 10:04 pm

Hi all

I've just started using this for suspension parts and some inner body panels.

Anyone else used it and if so, how did you get on with it?

I've painted it on as spraying is rather dangerous without respirators etc. Even though I did it outside, I took parts back into the garage, which was pretty smelly despite the door being open, so glad I didn't paint inside.

What has dried looks amazing. I plan to sand some of it and then paint over. Anyone done this too?

Yes, it's got warnings about overexposure and repeated exposure, neither of which I'm doing. I painted in the open but it is very strong smelling.

Interestingly, the bit I read about it was that the most important thing in making it work is that it is grease free. So I'm using acetone to wipe down before painting. If it doesn't seal, then it will has to come off and I wouldn't fancy trying that as it's so hard.

It's not a rust eater, so just wire wool and then paint. It encapsulates the trust and forms an airtight seal so it cannot rust again.

So far so good. I definitely would never attempt to spray this stuff. I don't have the equipment or the confidence!

I've used it. Don't use it on a smooth surface unless you get the appropriate surface treatment - I put some on the inside of my inner sills with masking for the area where I'd be welding so as to be able to put weld-through primer there. Once I pulled the masking tape off, some of the POR-15 came off with it as a skin, because it was clean metal and I didn't use their surface prep product.

Also, don't let it form a skin in the tin and then stab it with a screwdriver and send a spray of it over your face and neck. Took a few days to get that off.

Ive used this stuff aswel, as you say its an encapsulater and is great for suspension and the like but only if fully encapsulated ie no edges, I wouldnrt use this for body work with open edges, try googling POR15 peeling off in sheets, and then take some time to make a decision as to what you want to do with it.

That's really useful. I was using it for bodywork. I contemplated doing the floorpan with it because it does get water in there from time to time (a door seal or something that I can't determine) - and before I used Hammerite, which was OK but didn't seem to stop the rust breaking through if water sat there.

I've done a repair on a wing. A hole, which I dug out, scraped, wire brushed and then painted with POR-15. I have then used filler and gauze (Sorry :oops: ) to fill the small hole and again, put a coat of POR-15 on top of that to stop the edges being exposed. Finally, a thin skim of fine filler on top, sanded, primed and then top coat/lacquer.

I'll let you know how it holds up. I do agree though that it is fab on suspension parts and even when they are pitted, it forms a very nice shiny black bond. Looks good at least and from reports I read, seems to last forever.

There's a great youtube channel (Project Farm) with a guy who just tests stuff without being sponsored etc. He's really good and when he tested POR-15, he was quite impressed by it. I'll see if I can find the link.

Thanks again for the comments and advice.
