I have always been curious about the Tex coverings. When I cover with Koverall and seal with polycrylic I sand the seams until they are gone. If you are covering with a pre-painted covering do you sand the seams as well? My pet peeves (did I spell that right) are seams. I just cant stand to see them. Its why I switched from the film coverings. I am not good at all at applying those.
