I also had an issue with another brand of spray adhesive. It dissolved my release agent. Tried it twice with chemical release agent and wax, lost the part and mould both times. It was only the 3rd time that I tried PVA and then when I sprayed the adhesive I could visually watch it dissolve. 

I have to reply to what Nickvancamp1 says... I wont say it's not true, might work, but this is the problem I got once.

spray glue like 'BISON' works fine to, don't know if its available where you live.

You could try contacting 3M, see if they know someone in your area that stocks it? I thought I couldn't get it locally either, turns out there's a store within 5km of me that sells it

opss "hanaldo" heheh sorry spelling error 

Hi Halando, thank for ur reply.."Well the second spray is just acetone, that was used to activate the GC50 to make it tacky"

now i know..sadly i cant find that stuff in my local store, by the way , im from Malaysia, i did read post from others they

suggest to use 3M super 77 for the spray no1  too..thx alot buddy.

Well the second spray is just acetone, that was used to activate the GC50 to make it tacky. As it says in that message down the bottom though, the GC50 was reformulated and that no longer works.
