Sandblasting truck frame

Good luck you will like the stuff!! I prefer to brush the ZR you need to thin it 10-25% depending on temp i like to make it thin enough to spread thin but not run. i will try to get some pics of a trailer we just did. remember two thin coats are better then one heavy coat!!

 

If weather permits, tomorrow I am going to apply the ospho on my project trucks frame rails. Thankfully the typical paccar rust layer under the frame paint is there and makes scraping most of the paint off in big flakes an easy task.

I was going to leave the wheels on because I don't have a 1" drive impact, but I bought pablos "Torque multiplier" wrench so now I can R&R the wheels at home without the big impact.

Thanks for the tip on thinning the Zero Rust! I am taking my time on the project since the truck isn't under dispatch. I'll get some pix tomorrow and post them as I go along.

It really feels good to spend a little and get a lot in return with projects like this. Very gratifying for me, at least. Makes me feel like a kid again using naval jelly in a rusted out trunk pan of my '69 charger.

 

I'm going to scrape, grind where necessary and coat with the like of POR15 or similar.

 

A guy I know did that last year and his frame is still black. Not sure how long it takes the uv rays to make the por15 discolor.

 

I'm not worried about discoloration, just want to stop and seal any rust.

 

I sprayed on a coat of OSPHO yesterday on the frame rails of my project truck. It was mostly bare rusty metal as I had scraped off the majority of the loose material (typical paccar frame rail rust). In about 2 hours, the rust had literally turned black and seemed to have fully oxidized. Ospho is amazing. It did a great job on the rust, didn't melt any plastic or wiring- but did burn my face and arms when the wind changed direction and some mist got on me.

Nonetheless, I think one more coat sprayed on of Ospho (I used a plant/garden water bottle sprayer) then I'll be ready to shoot the zero-rust gloss black paint over it.

 

Were can I get Ospho?

 

Ace hardware is where I got it. They have it in their warehouse and can get it shipped to the store for no charge. I bought 2 gallons, and won't even use a quarter of a gallon on the truck- so I guess I can use it on my beams of the undersides of my van and reefer.

Thanks Visions, that sounds fairly minimal and effective.
