Power Washing
I have a question for y'all that have torn trucks down and cleaned them up to paint the frame and suspension parts.
I had planned on taking off the bed and front clip to clean everything up and paint with the black rust neutralizer paint that I have seen many of y'all use on here. My dad had the truck sprayed with an undercoating protectant when he purchased it and now 46 years later it is old, dry, and flaking off in some areas. Not to mention that it is caked over some of the bolts. My plan is to rent a 3500 psi pressure washer to blast all the loose stuff off and degrease while I am at it. That way it will be ready for some scraping and then painting with the black paint. I think it is the POR I have seen on here? I figured it would help with replacing all the suspension parts, reinstalling the motor and transmission, servicing the rear end, checking fuel and break lines, wires and relocating the gas tank. Do y'all think this would be strong enough to blast the loose stuff off? |

It will take it loose with a 0 degree nozzle, but be prepared to spend a while on it.

Re: Power Washing
ask your rental guy if he has a rotory type nozel for the power washer, they spin and aid in stirpping a surface down . they work extremly well .

Re: Power Washing
I tried it on my frame...and for 60yrs old it was reasonably clean....I gave up after a hour and a gal of purple power....I went ahead and pulled cab and took frame to the sand blasters. ...3500psi pw just wouldn't take the crud off...i tried all the tips..a steam jenny might have...

Re: Power Washing
I got the idea from blasting the dust off it before putting it in my garage with my electric 1200 psi power washer. It was strong enough to knock offthe loose stuff under the hood and wheel wells. I could see the lines it left in the undercoating. So I figured with some degreaser non-deluted and some elbow grease and that 3500 psi washer it should get it clean enough to paint over

I also found at a rental place here in Austin that they rent media blasters for $175 a day. That have a dustless version for $700 a day that pulls behind a truck. The 300 lb soda blaster is $175. Anyone have experience with a soda blaster? Never seen how they do on rusty metal.

Re: Power Washing
weve got a soda blaster at work...I wouldn't recommend soda...they're using coal slag to blast my truck

Re: Power Washing
the soda is very fine...like baby powder...and not very abrasive....it also has detergent in it...for a frame you need a more agressive media

Re: Power Washing
Anyone used anything like this before? Looks like an attachment to a gas powered pw that mixes the sand to blast without dust.

Re: Power Washing

Let us know how it turns out so we can decide if that system would be a good choice for us.

Re: Power Washing
Awesome. I always like seeing folks from my town. Seems like everyone is from up north. Anyway, I called Safeway Rental off of Manchaca Rd near 1626. I live right by there so it was the first place I called. It was more like $86 before taxes. But that price does not come with sand.

Re: Power Washing
That sounds good. Looks like theres one in Round Rock, closer to me. Be sure to post pics of the set-up and results!
