The Stovebolt Site Forums The Shop Area Paint and Body Shop Frame time - Which grinder do I use?

I'm getting ready to buy some tools to begin cleaning and painting my frame. I'm blessed this is a California truck so I don't have to deal with near the rust issue to the extent I did in upstate N.Y. This truck has light surface rust/grease /oil etc. The front clip will come off and i'll do the frame back to the fire wall and reinstall the clip. Then remove the bed and do the frame from the cab back then re-install the bed. Then to the body shop where they'll remove the cab and do what I couldn't get to before they do the body and paint. Anything wrong with this plan? I'm thinking of using a 4 1/2" grinder with a wire wheel after I degrease the area I'm working on.
The weight and size appeal to me. Any suggestions from those of you who have done this would be greatly appreciated. Thanks.

I used the 4 inch wire wheel (braided) on my truck with a 4.5 inch grinder. It does the job well. The deciding factor is how you will be painting the frame. The wire wheel will get most but not all of the rust so I used Zerorust as a base coat on my frame then covered that after a full cure with high temp engine paint. It has provided a good hard finish. If you plan to expoxy prime your frame you might be better off getting it sand blasted to remove all rust. It sounds like from where you will be it will not be that much further to get a bare frame.

The 4.5 inch grinder is very useful. I have one with a wire wheel on it, another for grinding and another with a thin metal cutoff wheel. Saves frustration of having to keep changing back and forth. Good luck.
