I was not entirely happy with the final finish as it was spotty and didn't feel or look right, so after a couple of long calls to Gavin, we worked out that the clearcoat mix was too thick. So I experimented by painting a piece of wood 30cm X 50cm RED with the paints I'm using, and then I sectioned it off into 6 squares. I gradually thinned out the mix until it was flowing nice and it gave me a completely flat and shiney finish. I was happy thinning the clear with around 20% turps. I did spend a lot of time perfecting this process, and I was completely happy with the end result. It looks and feels like glass. Blends it perfectly with the rest of the playfield.
Thanks again Gav
Only a small update, and the pictures don't do the finish justice.
I'll apply mylar rings and then give serious consideration to repairing the section between the flippers.
