Need to know more info before m how to add a second coat and when and how and what steps are recommended to take before adding a second coat? Doesn’t not tell you how long to wait for example do a second application after 3 months? Also, I wanted to purchase the product for $169.00 at 40 percent off but they were sold out after I checked multiple times. Anything you can do to help me get the better product? That I wanted and get me information or a video on the process and when to reapply it again after 3/4 months? Please advise at jonathanschwarz@askmcgrew.com
