Reinforcing fiberglass Mar 13, 2011 17:10:43 GMT -5

I'm converting a GT II to electric and like Mannyman, I plan on putting batteries in the rear seat area. The batteries will weight approx 200 lbs in the back and 140 lbs in the front. The backseat area fiberglass seems a little thin compared to other areas of the body. I already have a butt sag bar in place, so I'm not worried about that.

My question is whether to reinforce the existing backseat area with more fiberglass layers or use 3/4 inch plywood with contact cement and deck screws? Or is there a better plan that I'm missing?

Thanks in advance for your advice.

Matt

	Will finish someday, I HOPE!!!! Although, never really finished!

I did a stress test by putting 200 lbs of old batteries in the back. Later I drilled a hole to pass cables through and discovered just how thick the fiberglass is. This stuff is very rigid and from I can see, it will easily hold the weight I need to put there.

Thanks for the advice, but I'm thinking this is not going to need the extra support.
