A cheap tube of white tooth PASTE will accomplish the same results. Been using it for years. Haven’t used the UV sealant.
Yep. Toothpaste.
Pretty much any mild abrasive will do.
Toothpaste! Yes - it works, is readily available, and cheap. I use the Arm & Hammer type, then follow it up with auto-specific Plast-X, which is a combo plastic scratch remover and wax. I don’t know if it has a UV protector or not, but they look great when done.
TIP: have a spray bottle of water, and use it when you’re doing the toothpaste step. You need to keep it wet so you can polish the lens. Not so much as to wash off the toothpaste, but not to little or the cloth drags. When done the polish step, spray and wipe all of the toothpaste off, and dry the lens, then use the Plast-X.
