Hey, David!

[ERA Chas]

Hope you don't mind a couple of wacky questions.
I,ve read the polishing procedure described on your site. Assuming the thickness of material used is .060", [guess?] about how much material is removed in full polish [not Polish} mode? Does the skin "work harden" or become brittle? Will it dent-repair as an unpolished car or need heat annealing?
Also - on a car painted with conventional primers and two-stage color, approximately how much weight is added to the car?
Sorry for the anal questions but I've never thought about this stuff with fiberglass...
Thanks,

[David Kirkham]

ERA,

The material is 1.5 millimeters or about 0.060"

I do not know exactly how much material is removed. I would imagine 10-20% during a full polish job.

The polishing does not make the material brittle. The skin will work harden, like any metal, if it is cold-worked. Our bodies work harden when we make them.

I have no idea how much weight is added to a car when it is painted.

I don't know exactly how much a gallon of paint weighs...but assuming it's around the weight of water or gasoline (in reality it's probably heavier), it's about 8 lbs per gallon.

Let's be on the heavy side and say that a Cobra takes a gallon of primer, a gallon of base coat, and a gallon of clear. That would be 24 pounds.....

But that doesn't account for overspray and pot waste or what is removed during color sanding and buffing....But in a 2k lb. car with a 427...Who really cares?!?!?!?

I imagine 1/2 gets sanded, buffed, or blocked off in one way or another.

Maybe 10-12 pounds??? I think I could loose more weight at Weight Watchers.
