Billy, welcome to all things Optimum! Other Posters will have to assist with your questions about Reload, VTP, or Megs Tire Gel (Optimum does not test or comment on competitive products). Opti-Seal and Spray Wax are both compatible with ONRWW and both work as drying aids. I use OS due to it's greater durability, but it's a personal choice. I also use ONRWW on my interior with zero issues. Clay lube is for lubricity (should not effect clay performance) and ONRWW may offer greater lubricity due to the wax.
