Powder Coating wont work on wood, Its adhered the the surface [metal] with a positive/neg charge then baked.
There are a few other options available however, Paint being the most common. Vinyl, a nice replaceable surface [sega did this], but over time time,
heat/cold contractions will loosen the edges.... And laminate, this on requires some foresite in the fact your T mouldings may not cover the edge if
you dont allow for the thickness, and its kind of spendy to do it right/nice.... Jennifer likes the paint method [spray, automotive] best.
