MRBigg,


Isn't Armor-all silicone based?

If so, it is going to gradually coat the platinum glow element in your plug and there will be no possible contact, between the methanol in the fuel and the platinum catalyst.

No direct contact is no catalytic action, which means the element will eventually not retain its glow and your engine will just shut off, as soon as the glow battery is removed.

...And then you would say the glow plug is lousy...

Use only proprietary, non-silicone anti-foaming agents; like those used by glow fuel manufacturers; not Armor-all.
