That is very cool. If I am unfortunate enough to need to try this (I've been lucky the last few years with newer cars) I will give this a go.
Probable not. The blow dryer might warp the plastic.do u guys think this will work on plastic parts?
I agree with Chris and suggest it may not work. However, if you are willing I would like to see you do some experiments. Try it with just the CO2. Is it a big dent, which part is it in?do u guys think this will work on plastic parts?
