I just put a coating of Crystal serum light on my black challenger and was wondering if I could wait a week or so to put the EXO topper on? I live in South Florida and it's winter here , so the weather is fine. I know they suggest putting the topper on 2 hours after the CSL, but things have come...
Hello. I am wondering if there is a way to tell how old my unopened bottle of Crystal serum light is? There is a code on the bottle but I have no idea what it means. It is 39L121F813142. Does that tell me when it was made? Thanks.
