How to treat my frame

I worked the graveyard shift last night and read everything I could about putting rust prevention on my frame. I did get it sprayed by Toyota, but that’s starting to come off. Here are some pictures where you can see where the spray Toyota put on is perfect and some where not so much. Any personal experience would be great with whatever products y’all recommend

 

Most common theme I see in here is wire brush as much of the rust off as you can, spray area with rust conversion spray paint, treat with fluid film once or twice a year.

 

^ That's exactly what I did.

I spent an afternoon underneath the truck with a set of wire brushes and my electric drill, then I painted all surfaces with a rust preventative paint. Once that cured (I gave it a month), I coated the frame with Fluid Film on both the outside and the inside. I coated the inside of the frame until the FF was actually dripping out of the holes.

This also gave me the opportunity to apply the Fluid Film to other important components, such as the linkage for the parking brake and spare tire cable mechanism.

 

I was in a similar boat as you and being a poor broke college kid never had the money to fluid film or the time to wire wheel the whole frame. Needless to say, about 6 months after the extended warranty ended, I had holes in both sides of my frame, under the bed in the back wheel well. Ended up welding it back together and adding frame stiffeners, with a coat of POR 15 over it. Eventually looking at a frame replacement, but the plating should keep it good for another decade.

 

Yeah the POR15 is the route I would go. Fortunately I don't have that problem, (I live in the SW), but ive had buddies use that stuff on some old Foxbody mustangs and have had good luck with it.

 

Did my whole truck with a wire wheel and flat black paint. Used ospho on some areas but the chemical scared me . Once it dried I fluid filmed the whole frame. It’s a long process but worth it in the long term

 

I recently POR 15'd the rear part of my frame and my axle housing. I only had surface rust from driving and camping on the beach in Baja. It turned out pretty well. At some point I'll need to paint the front of the frame.
Before I go down there again I'll coat the frame in Fluid Film

 

How hard of a project was this? Looks like this is the route to go as far as getting the whole frame

 

Most of the work was in the prep. It was mostly surface rust so that wasn't too bad.

I took the bed off and I have a second gas tank where the spare used to be so I took that out. The second tank got painted as well. I removed all the bolts and nuts in the axle housing and the cross member the spare hangs from. I plugged all the bolt holes with ear plugs. Eventually I'm going to replace my OME leaf springs with either Deavers or custom Alcans. I'll paint the rest of the housing then.

I pressure washed everything to get the bulk of the dried mud and sand off.

Next I wired wheeled as much as I could.

Then I used simple green and green 3m scrub pads and scrubbed everything twice.

After that I used the POR15 degreaser and the POR15 metal prep.

Lastly I painted it. I waited until the POR15 was just slightly tacky and added a second coat.

Some things I learned along the way -
I used maybe a third of a quart size can. A little goes a long way. Get a bunch of the 2oz cans. Once a can is opened and you pour some out when you replace the lid you'll never be able to open it again. Put 2 layers of plastic wrap on the can before replacing the lid to prevent this. The smaller cans will reduce the need for this.

Read up on how this stuff cures with humidity.

Paint out of a small cup, not the can. Any debris or unnecessary air on the paint in the can will contaminate it.

I used cheap foam brushes I got on Amazon. Maybe spend a little money and get less cheap foam brushes.

Make sure you have gloves, this stuff stays on skin for awhile. Wear a hat. I got some in my hair. I just cut that hair off.

There are lots more tips on the internet. These are the ones that I thought of right now.
