like to know if it's a good idea to sand blast the under side of the hood to get rid of the rust or spry it with rust killer then primer it to paint. What is the best way to take care of this. It's not bad but needs cleaning up so I can use the hood. Thaqnks for any help with this.

NO, NO, NO!! You do not want to sand blast any sheet metal that doesn't have stiffeners (tight bends) in it to control warp. And even parts like floorboards and heaver frame members and pillars can be made to warp by injudicious application of sand.
Hitting the underside of your hood skin will likely ruin it by causing warpage that you nor a really good body guy can undo.
Use chem, sanding paper, and a careful application of a scotch-brite wheel (on the hood frame members, not the skin) and lots of hours to strip the underside of your hood. And no matter what you use, be very careful about getting much heat on the skin. Useable OEM hoods are getting hard to come by so don't ruin your's.

Soda blast is what a lot of people do. The sand blasting warps metal badly sometimes. You can get awhole car soda blasted for next to nothing and you can leave in the glass and chrome

I'd follow up by checking for high and low spots if you can use a hammer and foul to remove them and them if you need to use light weight filler and then a good epoxy primer. 3 coats of that and bam good as new

I bet you developed a good case of tennis elbow getting that hood looking like that?

I suggest you do some more research on soda blasting. If you don't get off all the soda, it will lift the new paint. A two piece part like a hood underside is very hard to completely clean. I am going to strip and paint the underside of my '66 hood this week and I am going to use the Elbow Grease Method.

Just use vinegar after sand blasting or a good surface prep cleaner and plus dawn soap and wash it and you should be good. That's what you usually have to use for a faster method to strip aluminum

I have done it every way, grit blast, soda blast, sand paper, aircraft stripper. I prefer the stripper and sandpaper/ wire brush technique since there is never any warping. And yes, it does take elbow grease, but I spell mine Guinness not like Hakan!
