GT3 Bumper question.

I also put in a bid for the gt-3 bumper last week. I was under the impression that he closed the bidding because he did not get a fair bid. Then i took a look at his other products for sale and saw that he was looking for atleast $900. $500 is a steal of a deal........

I have read some post here, where people have been saying something about cheap fiberglass products.....is it that bad? I have no idea about what is good material and what isn't. Will the paint/shine still appear on the fiberglass bumpers in time....or is it just easy to crack.....

so is $900 a decent average price for a fiberglass bumper........
