Roger Lee,
I was reviewing the messages and saw where one of the guys was using WD40 to ease off the hoses, and possibly re-using the hoses. What if any, is the reaction of the hose to the oil content of Wd40? Is there any form of deterioration in this practice? If so, what is your habit?
Thanks, Ferg Kyle

I would not use WD40, it allegedly degrades to leave silicon oxide (sand/grit) which is not nice, its a definite no-no for switches as you probably know. I use the aerospace equivalent, acf50 or LPS 1,2 or 3.
Silicones are not good in or on GRP airplanes, like herpes you got them forever !

Hi Fergus,
I'm not exactly sure why someone needs to use WD40 to remove a hose then put it back on unless they just needed to replace a part? Yes hoses can be re-used if they are in good shape, not damaged by the removal or past a time limit. I am with Graham that WD40 should not be used on rubber parts. It was designed to be a water displacement and a penetrant. It can cause some degradation over time and or constant exposure. When I used to Mfg. dive compressors we always recommend to never use WD40 because of the issue on the rubber parts over time, plus it will creep, seep and wick where you really didn't want it to go, AKA in your breathing air. It is a good product when it is used for its correct intended purposes. I haven't ever needed anything to remove a Rotax hose other than a little pulling or a twist motion. There are products out there meant for rubber, but I don't think I would use WD40 on purpose or in any repeated fashion. If it was an over spray issue and wouldn't sweat it, but I wouldn't use it on a regular basis. I know there are people out there that would swear it is the best thing since sliced bread on rubber, but they really should do some good research first and not listen to their neighbor.
My .02 cents as they say.
Like all our father's used to say, "Use the right tool for the right job".
(Of course when this fails get the hammer)
By the way WD40 got its name when the company that developed it tried many formulas and stuck with the 40th. chemical blend during its development.

On a different note:
I read a few months back a scientific study on Mystery Marvel Oil. Actually there are more than one. I have heard the claims of many about how it was the greatest thing since we have been able to walk upright. Many use it when they burn 100LL. People add it to their fuel and their oil with all kinds of claims. They all swear and would fight you to the grave about how well it stops leading and how it will make an engine run like a top until the next ice age. The study actual found out all the chemicals used, nothing more than lubricants, and they found over long term studies that there is no scientific proof that is does anything. It's been around since 1923 and it would takes weeks to see all the post on the web about it. I tend to go with science most of the time since my neighbor never did a long term fact based study. It may have been a better product back in the early days when our engines weren't as sophisticated as they are today and a little more lube in certain areas did help?
p.s.
I don't really know why I wrote this post? Maybe I was bored. Maybe WD40 got me going. Maybe I was looking for a can of worms to open? Who knows.
