So the copious snow from December melted in a flash and with the warmup I got outside to do some blasting. My main concern was what would happen to the plastic chrome, if the blast was strong enough to take the paint off. MyCB750K6 sent me 2 to experient with, one plastic on top and one metal on bottom.
At about 60psi the black comes off the plastic easily, and leaves the chrome shiny and intact. It is chrome under the black, BTW. It takes a lot more pressure to get the white to budge, but still seems to leave the chrome. I didn't try too hard as my emblems have black and chrome only, no white.
It took the black off the metal easily, but what is left behind is orange in color.
So for my purposes, success. I would consider just stripping the black on my K2 emblems and leaving the whole "750Four" script in chrome.
Of course frankenstuff may come up with something as well.
