There are people on this board that have seen the Jeeps and can vouch for the repairs being good and strong. Best of all it is cheap.
Thats all fine and dandy that you used thinner than original material to repair part of the structure on a Uni-body and Happy with it....
I myself wouldn't do nor suggest a less than original designed material on anything body or especialy frame related on anything,(UniBodies depend on the whole body as structural strength since there is no seperate frame)you generaly want to supercede what was original to strengthen things when repairing,especialy in this case where the original had corrugated bends in them for stiffness/strength for a good reason.
This is why you'll generaly see people doing such repairs go a little thicker than original to put the strength back into it....
The best option other than buying new replacement panels would be go to the local steel supplier and buy some 18 gauge or thicker sheets...the prices will vary in different areas and even different suppliers in the same areas...for example..i am working temporarily with a little maintenance company in Savannah Ga to fabricate and install a few things in a Mica plant that makes Mica and paint pigments for paints and women's makeup...we were calling 3 different suppliers to see who had the best prices for 4'x8' sheets of sheetmetal build a frame and skin it for "reactor" repair,which is just where a mixer that mixes active chemicals together and it "reacts"....
There was a HUGE difference in prices between them..so call around and see who has the best price on 18 gauge or thicker 4'x8' sheets of HRS(Hot rolled sheets)..Cold Rolled Sheets are more expensive because it has a finer process being made and smoother surface for less work to be finished off and painted.
A 4'x8' sheet of 18 gauge around here can be had for less than 20.00..i don't even know if you can buy a used hood less than that if you don't have a few junk vehicles laying around in your backyard...,and being less than original thickness and having to cut it all out off the hood frame..clean it up..prepare it..etc...
The new sheetmetal has no extra work...and cheap to buy new.......
You can also go even cheaper if the floor pans only need spots here and there and get some scrap peices from a local sheetmetal or Fab shop...or even buy or ask for scrap peices from a steel supplier..some will sell cut off peices for pennies on the dollar or even better yet..give them to you for nothing
