What's everyone's opinion? I have been using a professional grade sealant that AG doesn't sell with decent results. However, I am interested in the aspect of wipe on and walk away. I know Prima isn't this way but the application does seem nice. Whats the difference between them? Whats your personal favorite and why? What color paint works best for what? Gloss and slickness? Most times a nuba will be applied after. Thanks everyone
