Posca is easily removed from glass, making it ideal for temporary signs and window art. Once dry, you can easily layer over the top to build your design and correct any errors. Alcohol free, solvent free.
Seems to be more with power from what I can see with non V-limited Type RAs anyway.
Both mine and my cousins white one are electric and a few others I know here at home are too.
My old V-Limited No. 288 was manual and my mates No. 083 is also manual.
I have a set of manual windows and door cards but not too fussed about putting my current car back anytime soon.
