so last year i tinted my tails with vht, but now i want them a shade or 2 darker then how they are now, i have a little bit left do you think i can just spray on like one or 2 more coats or do i have to start over again and get the existing nightshade off.

 

i let mine dry and then put another coat on and they got darker so i would say clean them up and just spray over them again.

 

clean them and wipe with a prep wipe to get dirt/oils off and coats them again. dont forget the clear
