I am putting together an 85 F250 that will be sandblasted before I start putting her all back together. I have done a lot of research on what to paint the frame so that it will withstand the most abuse and such but there seems to be a lot of different ideas. I thought i would come to the guys who would probably know the best and ask them what they thought. I looked into por15 but they don't suggest that on a sandblasted frame. Powder coating would be nice but its a little out of the price range. Any ideas I would appreciate it. Thanks for the help guys.

 

I think just por15, then use an enamel black paint over that. por15 by itself is supposed to fade over time, which would look bad.

 

POR does not work well on clean metal. the name stands for : Paint Over Rust

 

Yeah thats why i dont want to use it.

 

I use Rust-o-leum.

 

same here.
i treat the frame with phosphoric acid, then a good 2 coats of rustoleum red oxide primer, then 2 or 3 coats of rustoleum industrial gloss black paint.
paint and primer are cut with acetone and sprayed on.

 

Ask Paul about POR15

 

I painted my 78 F250 frame with Sherwin-Williams Industrial Enamel Gloss Black. Lasted many years in the sun and weather till I tossed it. . .I painted the front end of my 87 F250 when I had the motor out with 2 coats of Rustoleum Industrial Enamel Gloss Black and it is still shiny. Only prep was scrapping a scrub with simple green

 

A long time ago I painted one of my Jeep frames with POR and it looked great for 2 or 3 weeks, but becaue the frame sat outside on jackstands while I worked on it in the middle of the summer, the gloss black paint turned Grey and chaulky in a short amount of time.

 

Since you are going to sandblast your frame, that would essentially be starting from new. If that's the case, I would suggest two coats of a good quality 2-part epoxy primer. I personally am using the SPI Home brand. I find it to be of excellent quality at a fair price, with the absolute best customer service. If applied correctly the epoxy primer will last for many years, after all think about how hard the 2-part epoxy glues are. Post some pictures of your work, maybe some before-during-afters. And keep us informed with whatever you do use and how well it holds up. Good luck.

 

Rustolium is your friend. Primer and paint.

 

Since I knew my ranger would get covered in mud and pressure washed over and over again, I primed and painted my frame with some hard enamal tractor paint I picked up at Tractor Supply. Been good for the last couple of years and is a pain when I need to grind the ground lugs and keep them clean.

 

Shut up Karl....

 

Don't make me send Paul over to POR15 your anus shut!

 

If you send Paul over it would highly benefit you to por15 your anus shut to before he gets there
