It's worth checking to know if your new Visor or Door Panel uses cardboard or masonite wood panels. Cardboard can bend easily, and may deform, especially when dampened by rain or snow. Even cleaning sprays working in around the edges can begin the deterioration process. TMI only uses masonite wood-backing.
Wood is the ultimate in lasting quality.
Why OEM grade is inferior. OEM stands for Original Equipment Manufacturer, or in VW terms, specifications over 20 years old. Specs for thinner, low tech vinyl. TMI vinyl looks like original manufacturer's vinyl, but it's 21st century hi-tech. The 250 count weave gives the carpet superior wear and stain resistance, as well as making spot cleanup easy.
