The Stovebolt Site Forums The Parking Lot Big Bolts 35 Chevy Fire Truck

Motor rebuilt, breaks around, wheel bearings repacked with new seals. The frame and chasis are ready for the sand
I am renting a commercial machine as a result of the advice seen here. Now for the "BIG BOLT" question of the day. Once the frame/chasis componets are clean after blasting, what happens next Do I immediatly put primer on the clean parts to keep them from forming rust. Do I use a special primer, chemical treatment or what? Pleas help.

Is the frame rusty or dirty/greasy or both? If it's rusty, I would primer with a rust inhibitting type of primer. But to answer your question, seal the bare metal ASAP.

If you have the frame blasted and that has removed the rust use grease and wax remover and epoxy prime as soon as possible. In areas that all the rust was impossible to get off use a rust encapsulating primer.

The frame and sheet metal are for the most part, rust free. There is the normal collection of greese/dust around spring bushing areas and any other zerk fittings. I have scraped/wire brushed most of the excess in these areas.
As far as the frame is concerned, it sounds like maybe I am close to sanding.
What are the pitfalls of sand blasting the sheet metal of the body? Will it be the same as the frame eventhough the sheet metal is thinner?

Use caution on the body. The blasting pressure and heat generated from the sandblasting process can warp and stretch your body panels beyond repair!

Best to take the body to a commercial blaster that has expereince with auto bodies.

You are better off taking your sheet metal to a place that will strip it by dipping. Much safer than blasting.

Thanks.....appreciate the input. It's tuff being a first time experience.
