Thank you for the awesome review and pictures NickD! Can I bug you to maybe do a video of each door panel since one isn't covered?
For all interested, this product is our standard Liqui-Damp product but we also offer a thicker version called Liqui-Damp X. NickD, I'd be happy to send you a free 6oz sample for more testing.
For anyone else wanting a sample, give me a call: 1-855-GTSOUND and request Liqui-Damp X.
