The trims on the GC 1, 2 & 4 come off very easy. Its the 3's that are a son of a b*!tch. I use powder coating on 99% of all my GC restorations because of: durability, variety of color options, low maintenance and its very reasonable on the wallet.
I use
https://www.prismaticpowders.com/ for powder and it takes 2-3 lbs for all of the metal on the table. They have an applicator locator on their site. I pay $225 per job, not sure what others charge, but, what I pay seems very fair to me.
I usually use the "vein" style coating, it has a texture and is smooth to the touch. The reason is because the metal usually has flaws in it. If you use a smooth powder coating, any imperfections in the metal will show. The vein style allows the applicator to build up the coating and it fills all the scratches and small imperfections.
If you are gonna play on the table a lot, in my opinion, this is the best solution.
Good Luck to you!
