Ok so my future son-in-law wants to help me restore my HMV. We have been going back and forth on the merits of having the body dipped in a costic solution or having it media/sand blasted.

So my question is this....Which is better and why?

Is dipping the body better for rust killing or is media blasting better. Both camps will tell you there method is the best...duh they want my money, but I thought the knowledged persons here might be able to shed some light on this.
