rust inhibitor front coil springs to pass judging

[Robert P.]

Looking for a possible correct rust inhibitor for the front coil springs that will pass judging for a 66
thanks

Re: rust inhibitor forn coil spring to pass judging

I don't know if what I am about to suggest or anything applied "will pass judging" but...... apply a coat of RPM - Rust Prevention Magic - easy to work with if you heat it with a heat gun - it is excellent for preventing surface rust...... for a long time - then, just before judging, heat up the coils a bit with the heat gun and wipe it off - comes off as easy as it goes on - wipe with a shop rag moist with denatured alcohol - and you are back to bare steel in seconds. Even when it is a thin coat RPM difficult to see or feel. Good luck

I agree^^^^^^

Bob, what if you used a flat clear spray bomb? I believe that with CDCIF there should not be a deduct if the springs are worth only a couple of points. It’s so much work removing and restoring these parts , and this will keep the rust away for years. This is only my opinion and not all judges may think like me. Coil springs were not coated from the factory so technically what ever you use it is still coated. A couple of light coating of fat clear makes it look natural and no sheen.

Re: rust inhibitor forn coil spring to pass judging

Makes sense - I was suggesting a rust inhibitor for bare carbon steel. Don't have an answer for the black treatment Bob is asking about. For what it is worth, RPM really works great - for bare carbon steel.

I have some stuff called Black Oil. It sprays on as an oil but hardens to a grease. It might be worth a try to see if this is what you are looking for.

Any detectable coating will not pass judging.

Added for correction: Any detectable coating, differing from appearance of original finish, will not pass judging. See Joseph Scafidi's comments below.

That said, your 1966 front springs total 4 points in Flight Judging. (2 Originality and 2 Condition points out of 4500 total points).

A detectable, non original appearing coating would be an Originality - Finish - issue under C.D.C.I.F. (Configuration, Date, Completeness, Installation, Finish )

All other aspects being ok, Finish only would result in a 20% Originality deduction - 20% of 2 points in this case. (0.4 points). Some judges might just write you a note, worst case would be a 1 point deduction (again, out of 4500 points).

i.e. don't worry about it too much.

If the judging guide states that a "black rust inhibiting coating is applied" why would any detectable coating not pass judging?

[Robert P.]

Joe, that is a very good question that i have not found the answer to
thanks to all for your ideas

You are correct that a "black rust inhibiting coating is applied" finish would pass judging. Shouldn't respond to questions in middle of the night!

Was thinking about parts that are bare.

Also, wanted OP to consider points at risk when making restoration decisions.

If the judges believe a rust inhibiting coating is not similar enough to the original factory coating, then I agree with Dave’s logic:

”Finish only would result in a 20% Originality deduction - 20% of 2 points in this case. (0.4 points). Some judges might just write you a note, worst case would be a 1 point deduction”

But if the judges are not using a cumulative “dot” system, then I don’t see how a 1 point deduction can be justified if the calculated deduction is 0.4 points.

As an aside, I would prefer to see the “dot system” (where one places a dot to the left of deductions <0.4 points, and then takes a 1 pt deduction after accumulating 3, 4 or 5 dots) officially banned. But that’s a topic for others to decide. I know there are folks who use the dot system and others who don’t.
