Hi,

I've heared about the good results of the 3M 77 glue, but I think any spray glue would prolly work. Be carefull however cos some glues spray thick stuff, while you want some kind of mist, like a color spray can or a spraygun.

In any case i would make a small test sheet to verify compability with the glue and your release agent. "We never know".  

Any updates of your car?

You could try a dab of uncured mixed resin if youre doing the lay up, bagging and infusion in one go.

Also using resin would mean the surface finish shouldnt be effected.

Being uncured also means when you pull the initial vacuum, you still have a bit of play in the fabric as sometimes when its all pulled in by vacuum, things move around a little bit.  Also means you can adjust it once bagged too.

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
