I recently replaced side art on a friend’s Mandolarian. Pinfidel did a nice write up but there are a few differences with a Spike 2 game versus BLY/WMS Here are a few:
1) Stern decals are sized to fit and don’t require any trimming.
2) you don’t need to sand a Stern Spike 2 cab. Simply peel the old decal off and wipe a dirt residue clean. Stern’s cabs are similar to a melamine cabinet.
3) use the wet method. If you don’t, the material for Stern cabs is thinner than the old BLY/WMS and will crease as you squeeze the air out. They also tear VERY easily.
