Can anybody say, about how much Por-15 does it take to do an F150 frame? Will a gallon do it?

 

I'm sure a quart would be enough. I bought one a year ago and have done a lot of painting with it and still have half left.

Keep it in the fridge after you open it. Also, make your you scoop the paint out and don't get any drops around the rim. It'll seal the can shut and you'll have to cut it open.

Make sure you prep or it'll flake off.

 

Ok, finally able to view the image. Had to log into google for it to work. That's really bad, I as well have never seen a 2004+ that bad.

If you use a rattle can, the rust will just come back. Use por 15. Also, think about getting wheel well liners back there to prevent the gravel from continuously doing the same thing.

 

POR 15 is basically the best if applied properly.

What I used was Tremclad (or if you live in the USA Rustoleum- same company just different branding). I used the Oil based paint. I knocked the loose stuff off and washed with a pressure washer before applying. I only did one coat. I can post updated pics if you want.

Winter is almost over for the year up here in Canada and I have neglected my truck more this winter then any other and the paint is not flaking, chipping or anything. Still looks like the day I applied it. My plan was to krown over top of it but I didn't get around to it.

I think this oil based paint is a great alternative to POR 15 and at a fraction of the cost. check out my build thread for some pics.

Wow thats pretty bad for no salt?

 

He's kidding himself. I spent 2 years in Chicago before moving to Ca. a lifetime ago. Back when cars had steel bumpers 1/8 in. thick I have actually seen cars a few years old (not very many yrs. old) where the bumper had rusted through from the back side and the chrome was still good on the outside. Chicago used so much salt on the streets it couldn't possibly freeze, just slush. The sides of ALL the cars in the middle of the winter were WHITE with salt. You couldn't tell on the sides what color the cars were. I know that is extreme but being from Ill. I can assure you that truck has seen SOME salt.

 

Of course it has seen salt. I've lived in northern IL for 42 years and I am well aware of the effects of salt on steel. I can also tell you that I have driven a half dozen vehicles to over 250K miles each, and currently own two vehicles other than the truck, all of which see similar driving patterns and none of which have this level of rust. There really isn't a whole lot of salt in this area where I live since any salt runs off the roads and into the fields and has an effect on the crop land. There is salt in town and there is salt on the state highways and tollways, but that is a minimal amount of my driving.

I'm not really interested in the reason why there is rust, I am discussing methods of stopping any more and protecting what is there.

 

What I want to know is this:

Why wait until the frame is this bad before action is taken?

 

It's getting off topic, but por15 would be my choice. I'm doing that soon to mine. About a year from now I'm gonna start pulling the front end off mine when I upgrade it and will get all the new parts coated.

 

Not everyone has all of the desired funding at the required time.
