How to apply Boeingshield T-9 anti-corrosion coating

[ccondit]

Does anyone have any experience/advice on how to apply Boeingshield T-9 anti-corrosion coating to the inside of the wings, fuselage, etc.? I've heard that if you use too much and it seeps out along panel junctions.

I think all of the corrosion treatments seep out along the joints to some degree or another.

I would think you would want it to seep out just to be sure you get into all the nooks and crannies.

They have a website where questions may be directed. Unfortunately, no videos or area descrbing applications.

I have looked at several aircraft with anti-corrosion treatments, including T-9. Once the stuff is sprayed into the wings...it's permanently there... so consider the fact that good OR bad... it's there. It's impossible to clean out and it leaves a waxy residue as a method of achieving it's goal.

It can be purchased in non-aerosol bottles/jugs, and can be sprayed with a garden sprayer...or misted with a vacuum blow-gun similar to how your mechanic washes down your engine compartment. BEWARE: the carrier is similar to butane, and until it evaporates is FLAMMABLE. Regardless of which method you use,...but especially is you mist it with a blo-gun... wear a respirator, avoid the fumes, and keep all ignition, sparks, etc. away.

Do it OUTSIDE away from the hangar.

Remove all fairings, wingtips, and covers when you blow it in. Let it dry several hours before storing back in the hangar.
Also, be aware your garden sprayer will likely have a short life due to the solvent in T-9 which will likely ruin the seals, so use a cheapie sprayer if you go that route.

I'm thinking there's lots of in depth info on the net on these products but from my experience I think the two products have a different purpose. Boe-shield does not continue to flow to the same extent as ACF-50. The Boeing product when applied properly (a very thin layer) it is almost transparent, which will not hinder future structual inspections. I've used both but ACF-50, I believe to be a product that needs to be renewed as it seems to flow forever.
In my case I live in a maritime environment (on the Pacific coast) so I'm a believer in corrosion control. I think depending on where a person lives or the operating environment, they may have a great need or little need to apply a CC product.
There's no down side to applying these products when done properly ( (a bad idea would be to apply to the gear where dust, sand and dirt when binding with the product would turn into a grinding paste but that should be common sense) and probably why we clean the wheels, tail wheel assy., wheel bearings and repack with grease at least once a year).
I've seen a few concerns where a low surface tension product is believed to compromise rivet grip. I think there's quite a few rivets going along for the ride in every aircraft, especially in a non pressurized fuselage and the fluids are only identifying those slackers. In either case, identified or not, I wouldn't lose sleep over it if there's no relative movement between components.

Please wear a respirator when using T9 . All you need is a spot of it in your lung and YOU are going to have a very bad day. Googles worn also is best . So be very careful.
