i've read on some magazine (forgot which one) that there is a special knife shops use to install clear bra. it supposedly cuts through the clear bra, but wont harm the clear coat.

if anybody knows where i can purchase something like this, let me know.

 

i think this is what you mean:

and as long as i am at it... on the subject of good articles on clear bras:

good article... not on point, but its a good article anyway!! :

My bra was precut by a computer and a waterblade was used to install.

 

How exactly does this knife cut the material but not harm the paint?
