As far as painting goes... I just buy the standard paints you find in department stores, but never anything that 99cents. Something that's at least a few dollars. The cheap stuff tends to cause problems.
AWESOME! Love your work dude!
And the bends you're getting out of these keyboards are incredible! Really inspiring stuff and something that I'm aiming for with my projects. You've certainly raised the bar on what's possible with a Hing Hon, that's for sure.
I get a little scared sometimes of trying out new types of paints, adhesives, cleaning agents, etc. Especially those with solvents in them... for fear of melting the plastic keys or causing irreparable surface damage to the finish. I've had a few bad experiences with some in the past. Examples of what I'm talking about would be... using eucalyptus oil to clean professional synthesizer keys then doing the same on cheap, plastic toys and watching the plastic slowly dissolve and melt, whereas on more expensive keys they clean up beautifully. With cleaning agents, you can at least jump in and reverse the damage, in most cases, and clean it off then polish it back to original condition. But with paint, that's a different story all together!
BTW... I like the spatter look too. Very nice!
Now, just to decide which looks better... white on black or grey on black!
