A good frame for a boat trailer is welded and THEN galvanized. Don't any of you guys own a boat? I remember one of those shows, in grainy black and white, from the late '50s that showed a Rambler being dunked in hot zinc.

Later model Lotus Esprit's all have galvanized frames. The zinc coating adds weight and cost. It also costs more to weld. The tips on the resistance welders must use a much more expensive materiel and they have to be dressed and changed more often. There are also toxic fumes that must be controled. The welds must be retouched after welding to repair the zinc coating. You have to keep in mind that the costs of building the car kept going up and it was taking them longer than they had planned to get the first cars off the line. For all we know the epoxy coated frame was only used to get things going and future plans would have been to perfect the EPRM or maybe galvanize the metal frame. What we have is really 2 years worth of production with a lot of it in the beginning rolling prototypes! On most production lines the product matures. They get better and better and cheaper and cheaper to build. DMC did not have that.
