Graphene Coating - how can I be assured old sealants are gone?

[intensifi]

Hello,

 

My C7 Z06 had Chemical Guys Hybrid V07 spray Sealant on it for a long time. How can I be assured it is all worn off before applying the Graphene coating?

I’d post pics of the current water patterns after a wash, but this site doesn’t look to support image uploads. 
 

Also is it a good idea to coat the OEM vinyl stripes?

Strip wash will take that off for sure. Also any IPA type wipedown will do the same. The V07 isn’t very durable

If you do a strip wash, machine polish & do a Surface Prep you should be good to go. 

Yes you can coat your stripes.
