My '87 short step 2x is gonna get a new dress, and I have removed the bed, doors, fenders etc (cab is still on) but I'm looking at lots of surface rust on the frame where it is newly exposed. Nothing structural but awful ugly. what is your experience with needle scalers, or blasters (?medium) or chemicals?
Time and Money are considerations as always.
Thanks for the help

I don't know of a way to do it well without a blaster. Most people that don't have that capability wire brush aggressively and use a product like chassis saver. You can use naval jelly and that kind of thing, but I think you're wasting your time on a frame. That kind of thing is better suited to small spots. There are places that can acid dip, but I think that's expensive and don't know of anyone who has done that. I can't comment on needle scalers, I haven't used them for rust removal. I would think a wire brush on an angle grinder would be better.

The fastest way it to have it sand blasted. Some Powder coaters can blast it and powder coat it all at one facility.

That's what I did. I paid $450 to get it sandblasted and powdercoated. It was money well spent.

A needle scaler works way better than a brush. It smashes the rust off, A brush just polishes it! I just did a jeep frame yesterday. On the lift, with the body on. Spent about 7 hours scaling the frame, suspension, and axles. Then brushed on Chassis Saver today. I used Transtarts spray bomb under coating over any areas that were not rust on the bottom of the tub, and chassis.

This only took me an hour to blast. If you can find someplace that has a commercial blaster it is not a big deal at all. Half of that hour was spent setting it up and moving it to be painted.

I agree blasting is the way to go, but not to everyone has the tools for it.

If its going to be a one time deal, I think you should be able to rent a blaster.

A small pressurized blaster will work great too. It will just be more time consuming. I just mentioned the commercial blaster idea cause I could do stuff like that cheap for people where I worked and thought there might be somebody in your area that might set you up.
