Boeshield vs CorrosionX vs ????

[Zzz]

I'm gonna give the 170 a nice internal coating of corrosion protectant. Some have recommended Boeshield, others CorrosionX. Anyone here have an opinion one way or the other??

Good question zane.What about acf-50,read a few articles the military uses that stuff.

[Zzz]

ACF-50 is a commonly used small area application product where lubrication is the primary focus, corrosion protection secondary, as far as I know. It doesn't seem to be that popular for entire aircraft application where corrosion protection/abatement is the primary objective.

Hey Zane. If you belong to Cessna Pilots Association you ought to get on their site and ask the question. If you do not belong, then join. I am a member and in the early years of owning the 182, I was constantly on the site asking questions. I even took there 182 systems and procedures class. Best thing I did to learn about the plane.

This is the forum that I now spend my time looking at, but when I have a specific question on my plane I go right back to CPA for the hot stuff. If you are a member you can call and talk to one of there tech guys.

Thanks Zane for this forum. Some might think that you are somebodies imagination but I accually met Zane in the flesh. Now does he really have a 170.

We had severe corrosion problems with the Apache helicopter. Ever wonder why there is no Naval Apache? Or why the Marines still fly the Cobra? Anyway the Navy guy's are king of corrosion prevention, we learned a lot from them. If in a corrosive atmosphere, wash it often, do not let dirt accumulate in corners etc. as it will hold moisture. We settled on Corrosion X as a preventative. It really seems to work well, as long as you do the other things to keep corrosion in check and reapply it on an annual basis.
One note though. If you intend to paint anything in the near future, go on ahead and do it before the Corrosion X. It will weep out of everything, even watertight seams.
If Boeshield is what I think it is doesn't it dry into a coating of some sorts?

Zane, I ACF-50'd my 180 starting back in 1988 when I got it. I think it has done a good job of protecting. It does weep though the skin laps but I'm pretty sure the corrosion is stopped also.

I've used CorrosionX a few places on my Maule. It's interesting stuff that sneaks it's way into all the important places and soaks in pretty well.

Both Corrosion X and ACF 50 were advertised and promoted as entire airframe corrosion preventive programs. ACF-50 actually hit the market a little bit before Corrosion X if I recall correctly.

ACF 50 is also sold in small packages, but it was originally designed to corrosion proof the entire airframe.

I fog my wings with ACF50 every other annual using a solvent sprayer and they usually weep for a while but the up side is no corrosion yet. When ACF hit the market I believe there were some articles in the pilot rags about fogging the whole plane but with the Maule I just do the wings.

I stand corrected. My understanding was that it was primarily a lubricant with good anti-corrosion properties.

Any opinions on Boeshield? This is the one my IA is pushing.

Zane,
Find out if Boeshield dries into film. I think it does. If it does I wouldn't go that route. I believe it will accumulate layers over time if you reapply it. The Corrosion X does not dry. I guess over a long period of time it evaporates or something. It does need to be reapplied. I believe the Boeshield will make a mess over time. I think it dries into a film like cosmoline, just not as thick and will attract dirt.
Yeah I'm sold on the Corrosion X. It works and if for some reason you don't like it it goes away over time, in a year or so you can't tell it was ever there.

Zane'

I have used Boshield on my M5 while on floats with good results.

I use it all the time on the aluminum tube frame of my folding sea kayak. The boat is in the salt a lot and the lower tubing is bathed in sea water pretty much a week at a time.

The Boshield does not seem to build up like LPS. It is very thin so it flows into cracks and crevices really well.

I have no experience w/ Corrosion - X so I cannot comment.

Zane, Boeshield is what the prvious owner used on my plane. It was applied about 7 years ago. Next time you drive or fly to Grants Pass stop and take a look and then make a decision. I think it is great. I am sure corosion x is ok to.

Guys, I have a gallon of Boeshield sitting in the hangar. Thanks for the confirmation emails. I've been working on building the fogging wand.

You guys do your vertical stabs and if so, how did you get into it?

I buy all my supplies from Chief, and they only carry Boeshield and ACF-50 for corrosion protection. I've hosed all my cable rollers and pivots down with ACF-50...good stuff.

[180Marty]

I've been using ACF-50 since 1988 on the 180. I get it in the gallon jugs and the first time they sent a trigger squirter like a windex bottle has attached to a plastic tube that goes in the jug. I put the squirter as close as I can and aimed at the lightening holes in the verticle and horizontal and squirt away---it's messy but better than corrosion.

Messy is good when it comes to corrosion

Boeshielded the 170 a few weeks ago... it wasn't that bad. I picked up a spray gun at Harbor Freight for like $6 that was the ticket. No dorky 12 foot wands, this thing was a blast-fogger. It takes a standard air fitting, has its own reservoir, and an adjustable venturi tip that can produce a fine fog or a super douche blast. Poked it down the wingtip and fog came out the root, so with a few blasts here and there in the inspection covers, the wings were done.

Shot it in every nook and cranny on the airframe, vert and horz stab and all the control surface corrugations. The fun part was washing the smegma off the outside of the plane a few days later.

I recommend this easy preventative maintenance to anybody, whether you have a Cessna or a rag/tube job.
