You absolutely did inspire me to create something with this technique. Thank you! It's going to be a fake hood cage for my Zombie Outbreak Response Vehicle for Halloween as well as for Wasteland Weekend.
Good call on using the tightbond & you’ll probably want to clear coat with the engine enamel spray paint that I’ve seen recommended by another RU-vid channel for items that are outside. Mine was for an indoor haunt so the glue & clear coat worked ok, but I did still have a little shedding of the coffee grounds. They add a great effect so I hope you are able to perfect that for an outdoor item!
Another thing you can use is spray foam, make sure you have a thick glove on, spray some in your hand and rub it all over then paint. It looks excellent. Your way looks great too.
