I'm going to be getting a new spoiler for my car and i'll be removing the stock spoiler. the problem is that i have 2 layers of B Quiet on my trucklid. Does anyone have any tips or any info i could use to get the stuff off? thanks

 

only remove from where you need to , to get the new spoiler on

 

if i was to get a new car can i take it off my old car and put it on my new one? if so how?
