sorry for the late reply that is the kit i used however I wouldn't recommend to use the c1 side of the kit only because c1 is actually only supposed to be sold to professionals if you do a botched application of c1 it is a bitch to clean off the only way to get it off is to polish it out
however if you patient and willing to take the time and do the steps correctly c1 can be done quite easily
I would recommend if you're not confident just sticking to the following C2 or C1.5
also I buy mine from
