Why do many aftermarket bolts rust so fast?

[sherpaJL]

blurb from the interwebs:

• ARMOR COAT™ FINISH - Exceptionally corrosion resistant. Ideal for the most demanding, harsh environments where conventional fasteners quickly fail.
• PASSES 1000 HOUR SALT SPRAY - At 1000 hours Armor Coat™ is still providing complete protection while zinc plating, zinc yellow dichromate and even hot dip galvanizing have long since failed.
• 10 TIMES MORE CORROSION RESISTANT - In standardized testing, only stainless steel held up as well as Armor Coat™.
• UP TO 250% STRONGER THAN STAINLESS STEEL - Armor Coat Grade 8 provides 150,000 P.S.I. minimum tensile strength versus 60,000 P.S.I. and up for 18-8 and 316 stainless steel

Too bad those corrosion standards do not apparently apply to certain doors and hinges and hoods.

I'm sure it applies. But, testing won't preclude quality control variances. They only test samples.

Sorry, Roanie, I was making a veiled and sarcastic comment there about the all-too-common corrosion and bubbling paint on Jeep doors and hinges and hoods.

I’ve installed quite a few exterior mods from various manufacturers, and often the bolts rust quickly.

is there a coating I should be applying when I install an aftermarket bolt?
(By quick I mean within months, in summer Midwest conditions. No salt exposure)

PB Blaster, spray your whole frame once before winter sets in and your good all winter.

This is a gun oil test. But that WD40 Specialist seems pretty good.
