tomstas81 0 Posted September 27, 2017 Hello, I would like to aply Optimum Opti-Glass Coating on my new car. Last week I already used opti-seal on my windows. Will I have to remove this prior to aply the glass-coat or can I just top it off? greetings Tom Share this post Link to post Share on other sites
Ron@Optimum 74 Posted October 27, 2017 for Opti-Glass to bond, you need to remove any wax or sealant - Opti-Glass bonds only to glass. Share this post Link to post Share on other sites
