Picked up an incredible deal on a retro Smeg beer fridge. Worth about 4K brand new for a few hundred bucks. Only problem is the fridge does not have the top section, as shown in the picture. Finding a spare part has been fruitless. So I thought, lets custom make one from fibreglass. Shape a piece of foam and cover with glass, then paint with a high gloss enamel. Is it that simple i ask our friendly seabreeze community. I've never shaped a board before but have done various repairs on windsurfing boards. Do I need a special type of foam or can I just go with some common packing polystyrene foam. The piece would need to be approx 700 x 700.
