DIY quarter skins

Interesting thread !!!! I am shopping around for rear 1/4 for my Barracuda 68 fastback we were going to glue the 1/4 at the top with some stuff that the local bodyshop uses its approved by the vehicle repairers comes in a double tube like silicon but you have 20 mins or so before it goes off,
the resoning behind this way of doing it was that it leaves no gaps between spot welds for dampness to get in then all you do is weld each end front and back ,this bonding process is very strong if it is done right what do you guys think is it done in USA ? Im in the UK so things are different here but gas is still 12 bucks a gallon !!!! oil prices are down whats going on ?????
