removing rusty #8 and 1/4" bolts in my kit car

[Qweaver]

My MGTD kit car was covered in salt water in the last hurricane.  So I'm about to start taking it apart to completely rebuild it.  My problem is getting the severely rusted bolts out that hold the body together.  It's not a good idea to grind them because the heat will damage the fiberglass and there is a zillion of them.  I maybe able to just grind the bolt off carefully right above the nut and keep it as cool as possible.  Will Blue Creeper work for this.  I considered using a drop of acid.  That should not damage the fiberglass. I am going to use SS bolts when I put it back together. 
I'm interested to see what the inside of the engine and tranny look like.  I have a completely rebuild power train for the rehab.

I would try blue creeper

Blue creeper is the cure.  Just make sure you add a good portion of patience.

Blue creeper plus a small impact driver..

If all else fails drill the nut if you can get at it. Even if you don't go all the way through it should weaken it enough for you to remove it. Nut splitter if you have one will work.

The best you could hope for would be to break all of them. Six point on the back, six point on the nut with an impact that hopefully snaps them off. Quick, easy and you don't want to reuse them anyways. If you have the space use a small zip cut wheel to grind off one side of the nut and that should release the ones that strip without much heat on the bolt. I expect the washer will dissipate that amount of heat safely.

#8 and 1/4" bolts should be pretty easy to just twist off as r.man suggested.

Easy to say...hard to do in most cases.  The majority are phillips pan head,  heavily rusted and hard to get to.  No way to get the torque needed to break the screw.  I think that grinding off the screw right above the nut with a thin high speed air grinder is going to be the best bet.  Then use something like Blue creeper.  Maybe BC will do it without grinding...I'll try it.

Bottom Line...they are going to be a "B"    I still have the manual that I used when I built the car so I'll just do it in reverse.  I'm sure that the VW floor pan is rusted beyond saving so I will have to built a new frame out of square tube.  I would buy a complete floor pan if I could find one.

Anybody that is recommending anything other than bluecreeper has never used bluecreeper. Get some, apply to all the affected parts, and the next day, just take them apart.

Thanks Jeff, I'm ordering some today.
