Engineering Bulletin #35

[Couv]

I've heard two unconfirmed and only slightly plausible stories about the "red spring."

1. The red coating is an anti-corrosive.
2. The red coating is an anti-ice coating.

So now, you've piqued my interest. I'd like to see

Engineering Bulletin #35.​

I know SP does not support the DIY concept, but I would be interested to hear the "official" answer re the red coating on some first stage piston springs.

Also, if you could search the archives and give a brief synopsis of Engineering Bulletin #35 to satisfy my curiosity I would be grateful.

Thank you,

Couv

Generally speaking, at SCUBAPRO we've historically used red to ID an improved, inline running change spring. IE: MK10, AIR2 inflator spring, as examples. The red spay-paint on MK10 main springs, was again, an improved generation part/component. Red-spray-paint does not denote anti corrosion , nor anti ice.

Thank you very much, Harry.
