Blast Before Burning.

---

J_: I am working on 1970 Chevelle convertible and I want to remove the body from the frame. The mounting hardware is very rusty. What is the best way to get to the hardware? Should I use a torch or is there some other way to do this?

SC: I use a torch only as a last resort, when all else fails. Try a penetrating oil first, such as "Blaster". Drill a small hole in the floorpans or trunkpan and very liberally immerse the rusty weldnuts and bolts from the top. Let it soak overnight, then rap on the bolt heads to try to free them up. Try not to break off a bolt at this point. If they are still not free, soak them down again and repeat the process. If they are still not free, then go for the torch. Be very careful here, however, it is best to have gas tank removed and lines blown out before proceeding with the torch.
