Kirkland Fiberglass - Head Up Composites bumpers???

[78 LS1 TT]

I've done a search on here and didn't find anything on the quality of Kirklands products. I want to order a set of bumpers but after receiving junk from a different vendor recently I want to make sure Kirklands stuff is nice. Who has bought from them? Was it a good finish? Did you have to do any filling or sanding to make it right?

Thanks!
