I’ve just ordered a load more from Harrison’s Trim Supplies, as I have run out today having redone the near side panelling of my van. It had been done by a so called professional company (Sun Rising Campers nr Coventry) but was so shite that I could put up with it no longer. They had used self tappers throughout, having put cuts in the carpet to screw the panels in place and then glued it back down. GASH!!!!!
Anyway, those hidden fixings look similar to what i’ve been using, and have managed to completely redo mine, and change the colour from anthracite to smoke to give some contrast.
