This glue is supposed to be water soluble, it is not, water wont clean your hands or get the stuff of your rim or tub, it does self centre but thats it. i will use Mastik One as i ve always done.
Have used this product twice and still can't belive how simple it is to use. The traditional method is a stressful PIA in comparison. The mastic allows the tube to be slid into the correct position and delivers concentric even fitment on every occasion.
Used Magic Mastik for the first time on a new 88mm Wheelset..followed the simple instructions, just keyed & cleaned the rim with acetone then applied using the nozzle on the tube...the mastik came out lovely & uniform and was the perfect amount for each rim...pulled on the pre-strteched tub and rode the next day!! all good so far, product worked exactly as described..
