Since the frame and undercarriage of my 03 is surprisingly rust free I intend to keep it that way!
Was wondering if anybody has used POR15 on their Ex and if so how much would be needed to coat the entire frame and undercarriage? I want to keep this one a long time and living in the NE rust will eventually be an issue...

 

From the website

How Much Do I Need?

So figure out how many square feet you have to cover and order up!!

 

Lol -actually pretty easy to figure out - just thought I would check with anyone that has done it already. Stuff is usually just one coat so sq feet will work

 

I had a gallon and used about half of it

 

I would start with a quart and see how far that takes you. If you get a whole gallon, you'll probably end up wasting a lot of it. So far, I did my gas tank and the area around where the running boards attach. The can still looks full. The stuff really goes a long way.

If you don't have a lot of rust now, I'd be interested in knowing how well the spray version works. Probably a lot more expensive but you'll be able to get it up into places you can't reach with the brush.

As other members have mentioned, be really careful where you drip or spill it. I have a tiny drip near my eye that has been there for three weeks. Nothing can touch that stuff once it cures.

 

The stuff does go a long way, I ended up using most of the gallon between my EX and my brothers 4x4 E350 Van

If you follow the directions for resealing the can, it will last a while. Pour what you are going to work with into a pan and put the lid back on the can, it starts to cure with exposure to air, and use some heavy plastic wrap between the lid and can to help seal it and prevent the lid from becoming a permanent part of the can.

 

I wish I had read the directions about resealing the can

Now when I need to get more paint out of the can I have to drill a hole in it and pour more out.

 

Thanks guys - yes, I have worked with this many years ago and it is incredible, durable stuff. Plan on wearing gloves, long sleeves, googles and keeping my face away from the painted area so I don't end up with a "POR15 Mole" lol. I noticed that they have the spray too now and might get a can for the nooks and crannies

 

I think you`ll be better off using a cavity wax. ===RUST FIGHTER-I. much better and you can spray it in all the places a brush will not fit. it will get into al the seams. we use this product at work after body work and to coat the inside bottoms of the doors on cars/trucks with door seam rust history. my boss used it on his new 2014 F250. I used it on mine after doing some rust repair. I used the POR 15 under my X after scraping some surface rust off of it.

 

Ya, you`ll always want to clean out the lip of the can before installing the lid. and refrigerate it, it`s shelf life will last longer.

This stuff went on nice after I POR15'ed everything I could reach with a brush. Dries quick and it really got in deep with the 2 foot hose on it.
