NO NO NO NO RAZOR !!! AHHHH !!! Just use your blooming finger nail .... gesh dont use a RAZOR. It's just the risk involved, a razor wont no the difference between your paint and the sticker .... If you dont have fingernails (Which I dont but I was still able to use them to pick my dealer sickers off ) then use a credit card ! .. and use the hair dryer !
I did use a razor to take off the CIVIC and the HX but they were on there with foam sticky tape and thiers more room for error
