Are you pleased with its performance/durability? Any additional remarks would be greatly appreciated. Thanks, Ron

It produces a nice tough coat. I can't say what it does in a normal paint job but I used POR15 to coat the inside of a diesel engine crankcase and it seems to be doing a nice job. It's kinda hard to comment on durability until the next engine rebuild though

POR stands for "paint on rust". It has a faithfull following in my hot rod club for bringing old car parts back from the dead. It's only drawback is poor UV protection (degrades in sun).

Hi Ron
I have just used it on my diesel yanmars.You need to get the special metal wash that preps the clean sanded areas before painting.It is also a POR product Wear rubber gloves as it takes weeks to come off your skin.Do not allow one drop of sweat to drop in open can or else its ruined. Store in fridge after use

I've used POR for years. I'm also a classic car guy. This is one of those "it works like they say it does" products. On the boat, I've used it on several steel (not stainless) items, including the rudder arm, motor mounts, and prop shaft struts. I've also used it recently to touch up our Yanmar turbo diesel. They do NOT have a color that matches Yanmar's silver/gray. I mixed gray and black, and got reasonably close. We'll see how it does.

As noted, this stuff ONLY wears off. A few years back, there was a thread on a Jeep forum that was about the funniest I've ever read. A guy used POR to undercoat his Jeep, with a sprayer. Apparently, he took a break to "drain his tank", and didn't realize how much paint there was on his rubber gloves. The "stealth condom" and "wear it off" jokes were endless!

My experience is that, once properly dry, this paint is as hard as they come. It will take quite an impact before chipping.

It often frustrates in how it goes hard in the can/bottle before you have a chance to use it all. Moisture cured, so a good idea to buy only enough for your current job. Despite decanting carefully and re-sealing in smaller containers, mine has never lasted more than a few months.

I would be careful about breathing too much of it in an enclosed space (like an engine room).

mmmm . . . I used their 'silver' color and it was a very close match to my yanmar color.

regarding our experience - like most paints it depends on doing proper preparation before painting. If you do the proper two step prep (degrease and then neutralize the rust) its works excellently, but if you just try to paint it on with minimal prep it will peel up quite quickly (lasts shorter than rustoleum with minimal prep).

+1 on all products. Same prob with matching paint colours. The tim says it doesn't degrade just faded in UV. just paint with a colour you like over the top after.

Like bstreep mentions, do not get it on your hootus

Thank you, everyone, for the feebdback. I am going to try it this Spring on my Yanmar. They sell a starter kit online for $21.00 that has everything needed for the project. I am interested in seeing the results. Good luck and good sailing, Ron

Just remember with every job as always preparation is everything. Have fun.
