Don---In everything I have ever read about reinforcing fiberglass bodies with wood, It has said that if you fit the wood right up tight to the fiberglass, with no gap, it will create a "shadow" on the outside of the body when the body is finish painted with high gloss paint. Any time I have reinforced a body, as you are doing, I made sure to leave a 1/8" gap between the wood and the body, and glass in both sides of the wood to the body by using a 2" wide strip of mat, half onto the body and half onto the wood reinforcing on each side of the wood. I hope that what you are doing does not give this "shadow" effect that I have heard of. I will be interested to see how it turns out---Brian
