Sandblast or not to sandblast
Got a ? about the rust that just wont die, last year after the disasembly of my 76 GMC short bed pickup, i removed all the rust and paint from the frameand i got this stuff from the East Wood Co. and it was call'ed (corliss) wich is supost to be impervious to all kind's of road salt and road tare and grime. The frame sat out in the weather thru the winter, and the frame rail's seem to be OK but the A-FRAME has rust comeing back thru to ware this stuff is flakeing back off. I've got the A-FRAME unbolted so i can get in between it and the frame, just wanna know if it would be worth POR-15 or is it cheaper to get it sandblasted, along with the upper and lower controlling arm's.

Personally I would have it sand blasted, then prime it with a good grade epoxy primer (PPG DPLF74 is but one). Then I would shoot it with a high quaility single stage catalyzed polyurethane. I never have kliked the way POR15 looks.

Any idea about how much it would cost to get just the A-FRAME and the controlling arm's sandblasted.

Sandblast and powdercoat. You should be able to get it blasted for around $25 or less. Powdercoat will vary from area to area.

Thanx for the replies guy's, that sound's like it would be cheaper to sandblast than what it would cost for a gallon of the POR-15 or any of the other stuff, but as far as the powder coating goes i bought a set of lowering shackles for my truck and they came powder coated, and after sitting out in the open with out the bed on the frame to cover them from the rain and snow last winter, some of the powder coat lifted and they started to rust.

My experience with getting a frame powder coated (at least in my area) is that you can paint it about two to three times with a high quality BC/CC for the price of powder coating. It was going to cost me $550 for the bare frame. $150 for rear axle housing, and $150 for front end components.

sand blaasting
Now , something I know about. We do it for a living. As for cost, the pot will eat about 60.00 $ of sand and hr., we need a compressor to build air pressure to propel that sand. Now you goin need someone to hold that hose while its blasting that sand. and he's gotto keep it moving or you ain't goin have nothing left. My point is. it can't be cheap, but if its done right it will clear well. Well do prime after blasting, but with what, I just don't know. I'm sure it has something to do with what the finishing material will be. We've done hundreds of cars, and all kinds of parts, and make a good living, altho we a rich get (I do buy lotto tickets tho. I guess i'm trying to say, it good cleaning, I done my 40 chevy 2 dr. sedan, frame, and body, inside and out. But you goin have a lot of sand around when it thru to clean up. And its kind of like life, preparation is everything. What ever you decide on, remember, if you don't have time to do it right the first time, you'll never have time to do it over. lol
