After having the tints done the other day (as well as me having done some bits 'n' bobs in the past) the Water Vapour Barriers (plastic sheeting behind door cards to prevent any moisture getting inside) on my doors were in a bit of a sorry state. The thing that finished them off was having them completely removed by the tinter to get the door glass out.
The stuff used by Vx is not of the highest quality (there's a surprise! lol) and the tinting guy mentioned a place in the same industrial estate that sold much better quality stuff. So I took a trip and got myself a big roll of it and set to work at the weekend.......
Front passenger door with the Vx stuff on (held on by some gaffer tape after the tinting! lol)
Refitted with the better stuff
Not only is it a better quality material, it is also thicker so gives a bit better sound damping from the outside. A 'mod' that nobody will ever see, but makes an improvement.
Easy enough to do as well, just needs a bit of patience. Just remove door cards and disconnect plugs etc., remove the old stuff and cut out a new piece. The new stuff is totally self-adhesive which makes life easier (the Vx stuff you have to faff around with sticking double-sided tape around the edges). Cut out an oversize piece, tack it at the top onto the door and draw the outline required with a marker, then cut it down. Peel off the backing paper and carefully stick it all down. Job done. I just needed to detach the front door modules to get neat fit.
