Hi,
Maybe I can help you, I bought a cheap hobby sprayglue (brand; "pritt" It's a sprayglue you could use to glue paper and wood and all kind of materials for making some hobbystuff like picturewalls and so on) I tought it would work as well but the problem was;
When using the sprayglue I used in between my fiberglass parts, the resin didn't passed trough the fiberglass where I sprayed it, causing dry fiberglass spots after the demolding (using Vacuum Resin infusion)
Hope this may help you
