i am new to this so bear with me. last year my buddy gave me a 76 overlander, it is all original and in fairly good shape. the only problem is that my wife doesnt like the 70's era look.the exterior only has two spots that i want to repair,1 in the front where some idiot pulled it through low hanging limbs and the other is the real prob. the rear was lightly hit by trash truck picking up dumpster .his dad just patched the hole from outside then cut a hole in the shower wall to seal it from the inside....
