Boeshield T-9

[Rickk]

Anyone know anything about a rust preventative called "Boeshield T-9"?

I was looking for something to put on the metal of my new gun and the hype looked good, so I bought a gallon on impulse. I think it is just paraffin wax in a solvent... supposed to be good for protecting rust with applications every coupla months. It went on easy with a paper towel anyway... did all the metal on the gun in like 5 minutes.

Has anyone had any experience with the stuff beyond the marketing hype?

It dried rather quickly... I put on a second coat.

I don't know how long it will last, but it does look pretty.... my 5 year old walked up to it and pointed out that the metal looked nicer... an independent expert?

I have heard that Boeshield and BreakFree are similar.  My experience with BreakFree has been 100% positive.

G... totally different than Breakfree.

Breakfree is a synthetic oil/solvent/rust preventative. It was developed in the later part of the vietnam war to help with M-16's jambing in the crappy jungle environment.

T-9 is totally different... It does not appearr to be a solvent at all. It is pretty much a paraffin wax in disolved, liquid form. I did a third coat to the metall tonight, and put some on the wood as well. Some of the woodworking forums on the net mention it's use. It did make th wood look way nicer almost immediatly.

 The real question would be how well it holds up over time out in the weather.

It was developed in the later part of the vietnam war to help with M-16's jambing in the crappy jungle environment.

I think you are thinking of LSA here (from long ago personal experience.)  BreakFree is newer than that.  It is a mixture of lighter and heavier oils such that the lighter oils emulsify the heavier ones but eventually evaporate leaving the more protective heavier oil film.  I have kept chrome moly rifle barrels in the white for more than a year with only a generous coat of BreakFree.

Could be, but anyway, they are not the same stuff at all.

Sears is selling boeshield now for use on tablesaws and such, to prevent the enevitable rust.

 It is pretty much a really easy to apply, penetrating wax. It seems to dry in an hour or two to a nice, waxy film. The solvent apperas to be petrolium based, so if there is a bit of surface rust it seems to disolve it, and the wax coats it. What little rust I had in my gun from the rainstorm that lasted all week disappeared when I put the first coat on.

The weatherman says it will get tested this weekend, and also during the next week. I will give updates over the next month or so on how it holds up.

It just so happens that I have been tearing down an old engine and was searching for rust converters to turn the rust into a paintable surface and a rust preventative to protect the parts until they could be painted. I had saved these three web-pages that had "amateur" tests. It looks like from what these guys found that the Boeshield is pretty good stuff, however I couldn't find any locally so used Breakfree instead, it worked pretty good on degreased surfaces for the couple weeks it took to get a coat of paint on them.

Mike RC,
I have been using a product sold at NAPPA's  called "steel etch"  It is phosphoric acid.  I changes rust to black iron oxide .  It is used  for auto body work.  keeps the raw steel from rusting.  We use Bioshield T9 in the shop to keep the machines tables lubed and moving parts working smoothly.

MikeRC, there is more than one Boeshield product. You are referring most likely to the rust remover, not the protectant. I got a small bottle when I ordered a gallon of the protectant. I haven't tried it yet, but when I do I'll let ya know how it works.

I had a party here last night. I fired the cannon a few times, wiped the bore quickly with water when I was done, and left it that way overnight. This morning between 6AM and whenever I became permanently conscious (noon-ish maybe?, good party) we had a thunderstorm that dumped over 4 inches of rain.

I wandered out there to give it a good cleaning after the sun came out. The waxy film left by the boeshield was still there, looking as good as it did yesterday.

After I ran water thru the bore, I swabbed out the bore and the vent with Ballistol (one of the best black powder gun oils in the world in my opinion).

Some of the Ballistol ran over the barrel near the vent and turned the Boeshield to a gooey mess. I left it alone and it eventually sort of hardened. It probably needs to be re-Boeshielded in that area. So, there is a bit of incompatibility between the two chemicals.
