Having powder coated quite a few pinballs , I thought I would have a go at hydro dipping having seen loads of videos on FB and YouTube ( not myslef find someone to do it ) Twilight zone stepped forward as the Guinea pig for this experiment.
I located a shop really close by and selected a space type star field pattern for the metal work.
It's quite a long process, first it required the metal to be blasted then primed. The pattern which is a kinda a glue is added and then the metal work is dipped. After that it's washed and baked and then a few layers of clear coat applied.
A few pics of the first stages below .
