3M S77 spray (the new stuff)

Well,

After going to about 3 different home depots, staples, office maxes, and office depot I could not find the old S77. I did find an all black can with a purple cap but the first component is still acetone. I sprayed the back of one of the beds from about 18" away and it didn't melt away or pit. So the question is should I continue to search or is the new S77 reliable if used correctly on a zagi400x?

Parkflyer,

I did use it tonight, and misted the wing from about 14" -18" away with no problems before taping the bottom. For kicks and giggles I sprayed a piece of styrofoam about 2" away only to see the styrofoam eat itself.

It's a bit late to be looking for old cans of 3M77. All the old stock has been gone for at least two months in most places.

The beauty of acetone is that it can't help but evaporate almost instantly in open air, so by the time the adhesive mist reaches your foam cores, the acetone has long since dissipated. If'n you don't mind getting 3M77 on EVERYTHING, spraying it from at least 12" away is a way to get around having to find an alternative.
