Recomended spray adhesive

3M Super 77.  Dries clear and strong, does not yellow over time and short but sufficient tack to bond time for adjustments after application. 

Ditto on the Super 77. At Micheals they also have cheaper alternative brand, which seems to me the same glue. 

 

Just make sure to wear a mask and use in an airy place

 

3M also makes a commercial permanent brand spray adhesive. I'm a little leery of the 77 for permanent holding. It lets go. I used it to bond bristol board to green foam board for my city streets, and had a mess. The stuff was delaminating all over the place. Here's a new one tested by a builder of fantastic 1/6th scale air craft and has tested three kinds; 3M77, 3M90 and this one.

 

 

This one won the competition. It's strong, doesn't de-laminate, and has a very small droplet size that gives a very smooth coverage. If Barry Dalwig recommends it, I would accept his opinion. He builds absolutely amazing models.

Saw the stuff Scenic Express sells demo'd at York. Can has adjustable nozzle for getting it in tight spaces without getting all over everything. Super tacky and dries clear. I have the 3M stuff but the nozzle sprays a big wide pattern with no adjustability.

I use 3M Photo Mount - does not yellow, but a bad smell. I use a lot of 50% water & 50% white glue for scenery work.

I ues a lot of white glue for the first layer and then a 50-50 for the next and then the next.
