Have a 68 console that looked like it had been a seat for a 3 year old. It was a series of small cracks, the total, definitely weakening the piece. . On the backside, rough sanded it complete and "laminated" it with fiberglass cloth and resin. It's ugly as hell but strong and not seen. Cloth adds strength and the small cracks are not visible after refinishing it. It waa originally avocado green, and now black.
