when I was resealing my 135 I was searching around town looking for something in black but of course all I could find was GE1 in clear or white. 832 is about a 300 lb difference in bond strength compared to the weaker GE1
for tools I recommend getting one of the 1" flexible putty knives in addition to the razor scraper. use the putty knife/spatula first to remove the majority of the silicone and finish with the razor scraper. One of the kits with the 3 small wire brushes helps out greatly too. the stainless steal brush helps to get rid of stubborn patches of silicone and as a final check before wiping down with acetone prior to re-sealing. get some disposable rubber gloves for when applying the new silicone cuz it's a PITA to get off your hands.
btw just for reference I used about 2.25 tubes to re-seal my 135. I made the seams slightly larger than needed for piece of mind, but it's better to buy too much and be able to take some back than to run out and have to do it all over again.
