Five year repair? I would most likely cover it with 1/4 inch rock. But there are other finish products that you could buy in sheets and cut to fit with minimal edge finish issues.
Yeah on that site it says flat rate shipping for 11.99?
You want to sell any of those aeros? ...I know a lower is a lower is a lower and all will perform admirably but I hear a few uppers don't sit all nice and mated with the aeros thus a slight bit of wobble between the upper and lower, nothing that tension screws can't fix. Did you ever see that with any of your aeros?
