I'm on my 3rd tube in 2yrs.......you need to start flying some M's !!!! LoLI think I spent $2 for the last tub of it I bought, and it's going to last a long time.

Agreed.....another big, big factor often overlooked is: How easy will it clean up after use. I have used many types over the years and have settled on one [Slick 50] that not only does it job, but cleans up easily with just soap and water or baby wipes.Bottom line. Don't think because you're paying a premium price for a "premium" lube you're going to get better results removing the liner because you won't.

Tub, not tube -- I bet this is good for 50+ Ms!I'm on my 3rd tube in 2yrs.......you need to start flying some M's !!!! LoL
Dow 111 is really gummy and a lot harder to clean up than the products listed.Dow 111, I use it all the time, mostly due to I got 3 tubes for a gift at X-mas 3 years ago, only have 1/2 tube left.
I've used Vaseline up to J350/J420 loads. Once I began flying larger motors (54mm J, K and up) I switched to the high temp greases. Now, I use the high temp grease on all loads because I always have it available.Actually the Aerotech instruction specifically mention Vaseline. It's all I've used on cases from 24mm to the I1299N in my 38/480 case.
that's interesting - I've always used either the Radio Shack teflon grease, or SuperLube, which is apparently the same stuff for 2x price. I have never seen any issues related to it reacting with the aluminum motor cases. but the cases are anodized, maybe that protects it?Perfluorinated greases can react violently with aluminum at high temperatures and should not be used in rocket motors because fluorine is a stronger oxidizer than oxygen, and even the PTFE in the "premium" greases is not a really good idea.
Dow 111 is very good for lubricating o-rings and has a better heat resistance than hydrocarbon grease, but is awfully expensive for greasing liners, and doesn't clean up very easily as it's not soluble in most solvent.Dow 111, I use it all the time, mostly due to I got 3 tubes for a gift at X-mas 3 years ago, only have 1/2 tube left.
heard but never tried the Slick 50, Maybe I will try some
Don't you have to be L3 to fly M's?I'll gladly starting flying more Ms, as soon as you start sponsoring them....

Saw this used by quite a few people at MDRA so it's what I bought.I assume you mean the inside of the case or the liners to make cleanup easier and be able to extract the liner..
I use Synco SuperLube. I've never seen it at an autoparts store, though. I get it locally. You can also get it from Aerotech at their valuerockets.com website as well as online.
Hmmm. approx 2 dollars for small tub of vaseline vs 5 dollars for a tube of super lube.I just can't see using hyper-expensive grease on o-ring that are used once. One time I had a copperhead fail to ignite a White Lightening load and it was over a month before I could get launch again. I had to dissemble the case to insert a new igniter, so the o-rings were effectively used twice. (well twisted on twice) And I saw no damage, before or after launch, from the Vaseline attacking the o-rings. The flight was prefect, so I'll continue to use Vaseline.
Bingo!Hmmm. approx 2 dollars for small tub of vaseline vs 5 dollars for a tube of super lube.
Risking about 800 in rocket materials (my current 4" project) and dozens of hours of labor to using an inferior product to possibly save a few nickels a flight.... Superlube wins out for me.
No offense. Vaseline is perfectly fine for those smaller motors. As I said previously, I've used vaseline on large 38mm motors without problems.Sorry, sorry... didn't mean to offend anyone, remember I said all I had was 24mm casing. Granted I don't want to loose it, but Vaseline is mentioned by Aerotech and it works for me. I'm an unemployed disabled guy, I gotta be real careful with money. 50 bucks is a very expensive rocket for me. If I was spending that much cash on a rocket I'd probably buy expensive lube too.
You make perfect sense, if your assumption that Vaseline is inferior in this application is correct. Other then opinions based on the "more expensive must be better" thinking, I've never seen anything that says Vaseline is any worse then any other lube, and some valid explanations why it's better then some.Hmmm. approx 2 dollars for small tub of vaseline vs 5 dollars for a tube of super lube.

Vaseline does work; lots of us (including me) have used it.Sorry, sorry... didn't mean to offend anyone, remember I said all I had was 24mm casing.
