Silicon Spray for Protection

[LONG_KEELER]

I buy it quite cheaply in pound shops.

Is it any worse or better than conventional spray grease for rust prevention ?

I seem to remember outboard motor manufacturers recommending it .

TIA

Only areas I use Silicon Spray is to stop hatches ... car doors ... windows .... locks ..... latches etc freezing ..... I buy the cheapest largest cans I can ....

Never noticed any difference from expensive 'purpose made' variety.

In the US that would be a dollar store (vs. pound shop). Just a funny ideomatic difference. Lately, most of them have gone to $1.25.

In Spain they are called "Todo a Cien" ... i.e. everything @100 Pesetas, which was approximately the Peseta/Euro exchange rate when the Euro was introduced. Hence Lidl's "Cien" branding on some of its low-cost products.

I went to a dollar store in the US once and when I got to the till everything was a dollar + state taxes.

Silicone is good provided there is never a need to paint or coat over it. Other than silicone grease in very specific uses I avoid silicones altogether.

I hate that ... spent a lot of time in US and it always annoyed me that Sticker price was misleading as it was PRE tax price. AND that each state has different tax levels ... with such as California with often more than one tax applied !!

I've always understood that silicone grease was used for rubber and electrical only. Mineral for metal and vegetable for high pressure.

Used a lot in the motorcycle trade, ACF 50.
A very good inhibitor, albeit a little expensive but does last well if bought with the "buddy" spray bottle.

Does ACF 50 contain silicone? I think it may well do but they are a bit shy about admitting it and it's difficult to find it confirmed in print.

I recently refurbished my stemhead fitting which had an attack of electrolytic corrosion under the bolts. As I had no waterproof grease to hand, so gave it a blast of silicone grease; too early yet to see if it does any good.
Have also used it on motorbikes, where it seems to perform as well as the old favourite Vaseline and probably stays a bit better. Can't say I can confirm this though.

Says no silicon of you look at the details on that page.

Yes, I think they are being a bit crafty there. There is no silicon but there might well be silicone

Good point.

A long time user of ACF50 on my motorbikes, I usually paint it on with a small brush. It kind of stops existing rust in it's tracks but does need reapplying in areas that see weather. XCP rust preventer stays put for longer and is also very good...

I slather my bikes in acf50 for the winter, wash it off in spring - with some diffulty. It has the real drawback that it is sticky, so the bikes look like carp, but it works brilliantly. To the touch it's like a lightweight waxoyl

I use the silicone spray for genoa, mainsail and mast tracks. A real plus is you can use it on fabric/leather too without staining. Great for genoa sliding in foil and zips. I'll try it this winter on metal parts. As it's not sticky to attract dirt might be a plus.

I notice WD40 now does a " specialist silicone spray" which promises a number of benifits.
