I recently bought and used the glass sealant WITHOUT watching adams YouTube video and let me tell you, LEARN FROM OTHERS MISTAKES.
I washed, glass cleaned, applied the sealant BUT... DID NOT go over the sealant with glass cleaner to finish.
Overnight. Came out and STREAKS EVERYWHERE. I hate myself.
So today (the next day) I'm trying to buff the hell out of it using the glass cleaner, IT'S WORKING... but definitely gotta use some force to remove these streaks.
