I need some assistance on this decision and need opinions/ rationale for why you suggest the option that you do.

I have a 1990 SC 5spd that is my baby. She suffers from some underbody rust which claimed the floorpan and front IRS mounts to name a few.

I currently have about 85% of the car stripped out, ie. engine/ K-Member removed, interior removed, IRS removed, bumper covers/ GFX removed, etc.

What I want to know is should I get it chemically dipped, or just have it sand/ media blasted?

Please give your reasoning for your choice.

Thanks.

P.S. To get the car dipped or to get it blasted completely is going to cost about the same, so it is really a matter of which to do.

I personally don't have any experience with chemical dipping, but I do have a LOT of experience with mediablasting cars. Both methods have their own pros and cons. I would choose media blasting, simply because I am more familiar with it.

The only problem that I have with media blasting is that there will be pockets of media that they won't be able to get out of the car. Where with the chemical bath, you can wash away, or dilute the hell out of the chemicals where it sits in seams and corners.

Only problem I have with the chemical dip is that I've never done it before either. I've had plenty of experience with sand/ media blasting, and I know the pro's and con's of it.

Id personally go with the blasting. Ive done this before with engine parts and really liked the results. The chemical dip is very effective to. Hot tanked a few front end parts and turned out great also. I guess it just comes down to price, but since they are both about the same, whatever you choose will give good results. I just prefer the sand blasting because you know exactly what is coming out the end.

I would probably choose the dip, because you don't really have to worry about the guy that does the blasting, screwing up and warpping one of the many large panels on these cars. And like josh said, you can rinse out damn near all traces of the chemical.

Just curious for the future, how much (approximately, of course) would it cost to have the entire car blasted?

Depending on the place you go to........

I was quoted the price of $1200 for blasting the ENTIRE car....inside and out of EVERY pannel.
