Yes you can...go to the DIY section...There is a thread about the steps on how to do it...
Its easy but be careful. you can sand it too much or leave the heat gun on there too long. I have learned the hard way...
nnnnnooooooo. lolshould i sand it while heating it? fell me in bro!
nnnnnooooooo. lol
That would be terrible! if you need to sand your plastics, sand before you heat them. If you don't have scratches don't sand. Make sure you use a heat gun not a torch. Its pretty straight forward you only learn by doing.
Just use like 500 grit or higher, if you use sand paper thats too grainy you can scratch it up worse.
