Rail Protector

Can I use silicone spray as a protector and then use a regular gun lube for lubricant on firearms?
What I want to do is clean and de-grease my firearms then spray with silicone to protect against rust. After the silicone carrier solvents have evaporated I want to use a light gun lube only on springs, slide rails and points where metal on metal movement takes place. Will there be any problems with the areas where the regular lube and silicone overlap? Will combining cause any problems with corrosive acids to form or anything unusual?
I use bearing grease on my mil-surp weapons, and it works better than anything else I have ever tried. It keeps rust away in very high humidity environments, and doesn’t melt off in high temps during storage. For semiauto’s except AR-15′s, i think it is the best general purpose lubercant there is. Plus, if you buy a tub at Napa, it will last you for decades.
