So I finally got my flocking material. I think I have 4 ounces of the stuff now - probably a lifetime supply. I also sprung for an applicator - basically a small squeeze bottle.
It was more than worth the $2.00 I paid for it.
The flocking experts recommend paint as the adhesive. This makes sense as it can serve two purposes - it will cover the material in the same color as the flock (assuming you use the same color) and it will make the flock adhere to the object.
Here I am painting the speaker screen with thinned acrylic (water base) paint. This worked perfectly because it filled the spaces in the screen.
Fowl Flockers people (where I got the flocking) recommend doing it over a plastic bag in some sort of container, so you can recover any excess flock. Good idea.
It took me three passes, mainly since I wanted to get the whole screen covered.
I always try to clean up orignal fasteners unless they're too corroded or rusted. These two hold the eye tube bracket on.
I dunked them in naval jelly for about 30 minutes.
I also cleaned the whole faceplate with waterless hand cleaner - I use Gojo. The cleaner is so mild it will not take the painted labels off. I got 45 years worth of dirt off the panel. You just need a small amount of cleaner - it works wonders.
