ProtectaClearTrial Kit (4 Oz)

can this tolerate high heat? i am considering of using it on brake caliper covers

Do I really need to wait 4-5 days to have it cure? I am looking to use it on my copper kitchen sink and not using the sink for 5 days wouldn't be easy

I have a copper roof copula and a copper weather vane. which product do i need, protectaclear or everbrite?

My stainless steel sink rusts. Will this help protect and stop rusting in the sink?
