Por-15

unclekenny · Jan 3, 2019

I have a 2011 Ranger. I usually keep my vehicles until they start to rust, then its time for another. I really like this truck but it is starting to show signs of rust. Jersey winters eat 'em up. Has anyone used POR 15 to try to stop new rust from forming? It's not really bad now but if I live long enough I would like to make this one a 300,000 miler. Has 130 now and running like a champ. Thanks for any input you might have.

skip the por-15 and use 3M cavity wax and Fluid Film instead. Start with the cavity wax, get the wand attachment, and get in all the nooks and crannies. Inside of the rockers, cab corners, doors, where crossmembers meet the frame rails, between the outer wheelhouse and bedsides, anywhere water can get in and sit. Don't coat the entire truck in cavity wax because its rather expensive! For the rest of the truck, use Fluid Film to coat the entire underside of the truck once a year, usually right before winter. Its a lanolin oil and will protect from moisture and salt. It does wash off eventualy which is why you need to reapply every year.

If you want a cheaper route, a yearly oil spray is a good alternative.

I like it

I’ve read good things about por15. The point about liquid film and cavity wax are good ones. It’s getting about time for me to consider the same. Minor rust on the frame and the front bed mounts are starting to show the classic Ranger rot.

Por-15 is really good stuff but it can be a PITA as well. When it dries its as hard as a rock so you want to make sure you get any on bolts or threads or anything that may need removed down the road. Our body shop had to fight it to get a bed off because the customer had used it all over their frame and just coated EVERYTHING which means they had to start cutting off bolts and grinding the shit away just to remove the bed. Also be sure to use it all in one shot. They said if you don't use the whole can then you have to put the remainder in a plastic container with a good lid because if you use the metal can it comes in you will literally seal the can shut and wont be able to get it open. lol. I personally never used it but heard good things about it. It's pricey too.

POR-15 is paint, as opposed to a spray coating... So, for example, how do you get it on top of the frame crossmembers without disassembling the truck? I'd use it on a new build but probably not just for periodic rust protection because you're going to miss the spots that really matter, IE nooks and crannies. I agree with everything ZMan said.

Many thanks to all for the info. Happy New Year. Ken

Can POR-15 be sprayed on. That would solve the nooks and crannies issue. Seems to me that a 2-part epoxy paint would be about the same as por15.

Sure it can be sprayed on but if you're going that route how do you keep it off everything else? Trans, t-case, electrical components, etc? There are still spots that are going to be hard or impossible to get at with a paint sprayer too. The sprays mentioned above are more of an oily substance - I've heard of people applying stuff like that with a weed sprayer. The wand allows you to get into the hard to reach areas.

I can spray paint with a pump up sprayer too. Put the flat tip on and get into small cracks between leaf springs and other hard to get to areas. :icon_thumby:

Runs may be an issue though. Just asking. not trying to start a debate on how to apply POR15

Por-15 is fine if you want to make it black. If you're looking to protect from rust, repel moisture and salt, its not the preferred route.
