Hi
I fist used silicone spray around the year 2000 when the Merc I had the foot (hand) brake became very stiff. I was advised by a fellow merc owner and it worked like magic

Since then i still used WD40 to loosen nuts and oil hinges but started to not balck, greasy deposits.

I've read that silicon spray does nor degrade rubber and was not aware of that until 10 years ago or so

What are the main difference and is Silocne type spray better and not use WD40?

Thanks

WD40 is in fact a penetranting and moisture displacing substance for loosening stuck connections (and protecting from corrosion), not for oiling/lubricating moving parts. Yes, it lubricates as well, but isn't as good as proper lubricants for this.

WD40 also contains white spirit (mineral spirit) which causes certain types of rubber to swell and degrade. So you need to be careful when spraying the stuff round spindles & the likes.

Hi
Thank you
So I need to keep both.
You mean spindels as in lock/hinge parts - if so they dont have rubber.
Thanks

I was thinking tap spindles, pump shafts, etc.
