I had my entire tub sandblasted by one of those giant fire hose sized blasters. It did a great job, but it was very hard to get all the sand out for painting. It would be perfect if you are going for a trail paint job. Heck, I'd do it again regardless of the quality of paint.
I did my rig too and I used the biggest freakin blaster I could rent. It stripped everything very nice. You shouldn't have any problems with hte metal as long as it still thick enough. Hood doesn't usually rust through. Get info from a sand blsting place too before you begin and tellthem what you want to do and the finish you are putting on and all info and they can tell you what material to use. I would check pricing on getting it done cause it's not that bad to remove the hood and it is an easy item for them to blast and they know what they are doing. I accidentally ripped the cover that i had on the wind shield and blasted the wind shield and basically in about ...mmm... 1/2 second screwed it. But that's just me I'm sure you'll do a good job.

The guy came out to the shop to do mine. He had a F-550 with a big-ass tank on the back and was towing a V8 powered compressor. Took a couple of hours to do my frame, tub and a 32 Ford body. I want to say it cost $300 total.
I sandblasted my whole tube, fenders and hood with no problems. I used a small hand held sandblaster so it took about four ten hour days to do it all. Call me crazy but I had some time to kill. If I did it again I would hire it out. It got a little boring after a while.
I found the sand a little hard to get rid of before I painted it but it was no big deal since I was painting it myself for the trail. No showtruck finish for me. Good Luck, Bob
To keep things from overheating I used a sandblaster that attaches to the end of a pressure washer. Makes a huge mess but did a nice job. Took me a day to do my whole frame and misc. sheet metal parts.
