I finished them a few weeks ago but have been/am still making minor adjustments here and there to ensure 100% functionality. Using plexiglass, a plexiglass knife and a heat gun to create these was remarkably easy. They are very snug against the body lines. However, I did use DAP black latex caulking to seal the edges against the body. That stuff is very useful due to it have all the same physical properties are silicone caulking but it is non volatile and peels away clean when you remove it. Just a little tip...
