Glue spreader?

[Hardrada]

I've been using used VisibleDust sensor cleaners, sans the fabric-lilke cleaning pad.

I bought a bag of 1" paint brushes, there must be 20 or 30 in the bag.  I only paid a couple bucks, I have started using the water based contact cement and rubber cement so the brushes can be washed out a time or two then tossed. I also have some of the plastic paintbrush looking sticks I picked up a Tandy, they are good for small areas but get tedious on large areas like lining a holster.

Those black foam brushes. Squeeze them in the store to find the ones with plastic reinforcements attached to the end of the handle. Pull off the foam, trim reinforcement to suit the application and spread the joy.

Recently I purchased an assorted pack of Bondo brand flexible spreaders. The glue doesn't seem to stick to them and the material is able to be cut to width. They work pretty well and cleanup nicely.

You can make your own by cutting up old ice cream boxes, not tried it but heard others who have mention them
