steam clean or power wash?

Would like to know what others have done about cleaning the undercarriage. Would like to steam clean or power wash underside of my 63 before prepping for paint. I hate dirt in my face. The frontclip has been removed. So I am talking from the cowl back to the trunk. Also inside the cowl below the windshield area, how best to clean that. Also, can I wash the inside also, the body is totally stripped of accessories. Thanks.

If you have access to both I would power wash it first to remove a lot of the loose debris. The remaining patina can be stripped to metal or paint if it sticks with a Steam Jenny (be careful with both, but the steam will give you serious buns if it hits you and requires extra caution).
Thanks Big Dave. I think I will pressure wash and then get it sandblasted.
As far as washing it out. I had everything out of my car and I used a presure washer on all of it. From the roof to the huge holes in the floor I washed all of it and let it sit in the sun to dry out.
DO NOT SANDBLAST your Nova or any other car for that matter.
Sandblasting causes to much heat to use on sheetmetal, it will heat warp the body and make really wavey.
Check into media blasting ( its plastic shot insted of sand) it won't destroy the body.

Sand blasting is OK for floor boards, the trunk area, the front subframe or any rusted areas. There are varying degrees of media for differant jobs. Sand blasting is the second best way to get rid of rust, acid dipping is the first.

Yes it is true, sand balsting body panels is NOT advised, but it works nicely for other areas of the vehicle. Media or soda blasting is used for body panels.

Good Luck :D
Well IMHO I would stay away from acid dipping your car also.
I have some 57 Chevy pickup body parts that were dip stripped, it dose take out everything including rust, But on my parts everywhere there is two or more layers of sheetmetal iv'e had residual acid seep out eat off paint and primers that had been put on months after dipping , this chemical never really goes away , ALSO it takes everything out of everywhere like those places you can never get into to put paint back to keep it from rusting again. I would strongly recomend media blasting.
