Hi all. I am looking for some advice. I am ready to install my engine, and am wondering if it is advisable to install the Gray soundproofing blanket that came with my early 90s kit. Is it effective or not? I have seen pictures of it installed on this forum and some look pretty ratty,oil stained, and ripped. Plus the Kitfox factory aircraft dont seem to have any sort of material attached to the firewall at all. Is this something that proved to not be that great an idea? Or is it worthwhile? I dont think it is meant to be a fireproofing material, and that is a whole other issue.

Thanks Dutch
