I'm honestly not sure how the Kydex is going to take staples, hoping it will be OK. Will find out soon enough. I also have about 5 pallets of 1/8" MDF Pressboard in the warehouse if the Kydex ends up not working, but I'm confident it will be OK and last forever.I've not tried Kydex for door skins. When I redid mine I used mahogany door skins I bought at the lumber yard. To do it over I'd probably use 1/8" Baltic birch plywood. The door skins worked great, but I believe baltic birch would be even stronger. The one thing I learned is that staples were needed... I tried only using contact cement. In the summer it gets hot enough inside a 40 in the summer to soften contact cement and the vinyl then came off.
