i only got my hands on it as my car was on the ramps at Owell trucks in norwich as my GF's cousins dad is chief whip there so he pulled a tube out, cost about £50 and just plastered my door in it, thing is i need the removal chemicals they have if i ever need to sort out the window now

best is the buetyl strips, had some off ebay i was going to use but went the other way
best do that TBH, im still in two minds about it the stuff i've used but its working so far lol
