How much POR-15 would I need?

I just picked up a 1st Gen and the frame is solid. When Toyota issued the frame recall, it was still in great shape and they recoated it. But several years have passed and some of the coating has flaked/worn off. I want to re-coat the frame and keep it protected for many more years.

I was wondering, how much POR-15 would I need to recoat/repaint the frame? (I would be using a paint brush).

 

The toyota coating doesnt take paint very well. It does however, soak up fluid film like a sponge. I use that over top of the coating on my truck, keeps it real greasy underneath, and keeps the Toyota coating from flaking off as it revitalizes it.

 

I would bet 1 quart is enough. I painted the frame on my trailer & it took 1/2 quart.

That coating Toyota applied will trap water & accelerate rust where it is loose. ANY loose coating - get it off!
Also - look into getting some Fluid Film in a can & the hose attachment so you can spray F.F. into your frame after you paint it. you really need to do what you can to stop the rust happening inside the frame. I used shop vac &/or leaf blower to attempt to blow out the frame before I do internal F.F. treatments. Won't be perfect, but probably helps get some road debris out/ keep the drain holes open.

 

Some of it has 'broken' open and there is some rust.

 

Yup. I wouldnt even mess with painting it. Pick up 4 cans of fluid film down at napa and start hosing it down. It turns the toyota coating back into the greasy substance its supposed to be.

 

Wd 40 can be also used to prevent rust in a pinch, but fluid film is our go to on the forums

 

Here are some pictures of the frame.

 

it's a big project, but doable. Differing opinions here on the route to address.
My opinion - scrape off all the loose stuff, wire brush all the rust, POR 15, Fluid film.
POR 15 is not UV Stable, but POR 15 "top coat" is UV stable. FYI.
How do you eat an elephant? One bite at a time. Set yourself little sections goals.

And the beds come off really easily. My first gen it was 6 bolts & 2 wire plugs, & 4 screws at the filler neck.
So much easier to address the frame w/o the bed in your way. 4 people can lift it off & place it out of the way.

 

It's a project truck for me, I know its gonna take some time to 'clean it up'.

But it's an '01 with 262k miles out of north-western VA.

 

That last picture don’t look to good

 

It does look bad, but it's not. The black isn't a rust hole, its paint.
