First of all, as a longtime silent browser of this forum I would like to thank everyone who has ever contributed their knowledge on first generation Blazers. This forum is an invaluable resource! Due to the fact that I live in a humid and salty area of the country, I have been considering replacing my sheet metal panels with fiberglass (not to mention the weight savings). In the "Cancer Support Group" sticky post 71RestoRod made an excellent point regarding the maintenance of a Blazer's structural integrity in restoration. He also highlighted the front, rear, door, and hood panel’s contribution to a Blazer’s structure. I am not an engineer, but I assume that there are some negative repercussions to replacing semi-structural sheet metal with fiberglass, such as rigidity, lack of internal structural supports, and the lightweight of the paneling. I would be very grateful if anyone could post his or her thoughts on this subject. Also, any thoughts on fiberglass panels versus steel replacement panels are very welcome.
