Soon, soon ....
I have to find another 2 cans. Seems to be in very short supply/non-existent at the hobby shops that I know. There is another type made by Tamiya also - code is TS-71 Smoke. It is made for plastic vs polycarbonate - whats the diff?. Cap is the same as PS-31.
As an extension, I would suggest that u also spray clear lacquer on top of the smoke paint for added protection, particularly at the front. U can get cheaper clear lacquer from Ace Hardware.
Clear lacquer can also give ur faded tail and signal lamps new life. Just make sure the surface is super clean and if needed, lightly sanded with 0000 grit paper.
BTW, I had to use nearly one whole can for my rear lens (1 side only).
Pictures later, after I get home, if I can remember.
