Sandblasting the frame-question

Guys,
I have it all done, except the underside of the shock towers.
It's only some surface rust, nothing going through the frame.
Looking for opinions, should I just POR-15 it and be done,
or sandblast that too?
Kicker is I'm a little burnt out, sandblasting-wise,
but I value your opinions.
I only have the driveshaft and axle to go.....
hope to never see another sandblaster as long as I live....

Up to you. If it's surface rust, it'll probably rust all the way through....in about 700 years. You could POR15 or use a converter and paint over it, or leave it alone. I'll tell you what you already know, though. If you sandblast it now and do it "right", you'll never regret it later!!!!

I hear ya on not ever wanting to see another blaster. I blasted my entire frame in the driveway along with the driveshaft. The control arms I did in my cabinet. I let mine sit for a year and then coated the entire frame with 6 cans of Eastwood converter to prevent it from ever rusting again. I then painted it with Eastwood epoxy and it still looks new, but then it hasn't moved out of my shop in 2 years either...

Man, do I ever remember those kinds of feelings. There were many times building the Beast that I discovered some little part I'd missed when painting (of course after already cleaning my gun and putting it away, throwing out the unused paint, etc) and I'd stare at it for a few minutes contemplating just going with it. Eventually some little voice would chime in and ask, "do you really want to have to do this all AGAIN when it rusts later?". That got me going.

Great opinions

It's always good to hear I'm not the only one.....
thanks Guys, for your input and opinions.
I'm rested, so I guess it's time to finish her up.
The info I've gotten in this forum has saved me so much time, effort, and aggrevation.
I finished the cross member and the driveshaft yesterday, did them outside.
The frame is inside the garage, but I have alot of plastic that I can make a "tent" out of to minimize the sand flying about...I'm trying to keep the garage clean, that's one of the issues in my debate.
I'm trying to post a pic or two, but I get the message that the pic is too big for this format. I'll keep trying.
One more question: When I blast the rear axle, how do I protect the differential? Should I not blast it? It's not rusty, the paint on it is ok, just scratched up a little.
Thanks again.

IF you blast it....SAND WILL get inside....either disassemble it and blast it then clean it, or clean it up real good, and paint it! IMHO....E

thanks Eric. Even though I put it outside the garage when I was blasting, I know sand had gotten into the diff. I'll have to have it taken apart and cleaned. I've never done that before. Is it as complicated as the diagrams make it look?
