I have good experience with powdercoating. I brought a very sticky BeoLab 7-4 to a local shop, they sandblasted the empty cabinet (I made sure to put screws to avoid the threads get damaged or covered) and coated it with a light textured black coating. They normally make you choose from samples so you can choose how smooth or rough you want the texture. It does not feel rubbery but is much more pleasant to the touch than before and very tough.
I had some Beo4’s done as well and the coating holds really well. I can send a photograph tomorrow when there is daylight again if you want.
Hi, I tried to capture the texture of the powdercoating on my 7-4. I can tell it was a massive improvement from the scratched and sticky ‘before’ situation. But it also costed more than the speaker :-).
DanteM: A couple of other things to consider are texture paint in a spray can or Plasti-dip spray. I don’t know if these would be available where you are at, but they easy to find in the US (except for maybe California).
These would not be as nice as the powder coating, but would be easier to remove if you didn’t like the results.
