WD-40.... lots of!

[Jonny Boaterboy]

I read in one of the mags that spraying WD40 over ther distributer and leads will help repel water in the event you wade a little too deep...... well I'm a bit of a grease monkey and have got into the habit of compleately covering the whole engine in WD40...... Is that a good idea? One of my mates at work said to sear clear of WD40 as it is baned in the aviation industry for some reason? It does not apeared to have done it any harm however will it perish any of the rubbers or plastic or anything else? I'm awear of the fire risk (I'm a firefighter!). It would seem to make good sence to me as you will keep everything that moves in there nice and free moving (accelorator links etc.) it will stop the rust bug, repel the water and start to free up that sesized nut you need to get off! I also use Morris MD4, would that be better than WD40?

thanks alot Jonny

Thanks iain will try and get some sound like good stuff do you think sprying every thing else with WD40 is bad or should I just get it on there?

we know a guy that was spraying his 150hp outboard with WD while the engine was hot, up she went on fire and the boat ended up as a melted blob of GRP on the bottom of the lake.

WD40 is very useful in that it will displace moisture, so its the quick way to get a drowned dizzy working again. however ther are far cheaper and more effective forms of prevention.

On the cost bases allown i wouldn't wast it all over your engine bay.



As for any body that sprays flamable substances onto a hot engine, well they say if you can't say anything nice, then don't say anything at all.

WD40 used to contain silicone (now it proudly boasts it doesn't) and this dissolved silicone based devices and certain plastics, I was advised not to use it on my mountain bike as it damages the cable lining.

Also don't forget it free's rusty nuts, it was pointed out to me that wd40 is an acid, a mild one that it why you may have a reaction on some plastics. :shock:
