could u paint carbon fiber with this? would u have to sand the carbonfiber? and, wat sanders do you guys use to sand away? and canadian tire does tint the paint...so when they take the base and add color in to get the desired color...should i tell them not to shake it and go home and sit for 30 mins just stiring the paint? orr i have this thing "as seen on tv" where u can vaccum seal stuff...can i just put the can in the plastic baggy and then vaccum all the bubbles out?
