If you use the Evaporust on galvanized......after the Evaporust had done its job......what is left on the surface where the rust was? Galvanizing or bare metal?
Either way, if you just spray it with Boeshield afterwards, just doing that will protect it for years to come?
Boeshield it a great product however I have found a Dupont product which is a teflon based waxed chain protectant/lube. it works better, lasts longer and is 1/3 the price. PLUS... the wax base dries to a film without gloss and isn't tacky. Designed for motorcycle chains it resists slinging off, water spray, & etc.
If it was a larger pitted area I sprayed some zinc rich cold galvanizing paint on a rag and rubbed it into the area. same thing I did to the Gas tank on a survivor.
