a quick one : if u use an auto oiler where does all the oil end up after it leaves the exhaust ?? into fresh air or on the job ?

 

[danelectro]

It goes to exactly the same place yours does, the only difference is, the metered miniscule amount my auto oiler injects in a vapour form, is never enough to cause a problem, whereas your 3 drops have probably already exited onto the job in the first few minutes of use.

BUT, this discussion is not about where my oil goes, it's about the use of WD-40 in a da, which again I say, is not a very good idea. I'm sure there are many that have done it and don't have a problem, but frankly I am of the opinion that it's best to do things properly, and new folk coming on here to learn, would read things like "Yeah pump a load of WD40 into your da and it'll work" which really isn't a professional thing to do.

There is an awful lot of talent on this forum (in many fields), with long standing professionals that can really steer people into doing a brilliant job. But I think there are also a lot of talented people here that seem to think they know everything about everything, and CAN give out the wrong advice.

I have been spraying paint for around 30 years now, and up to now not had any problems with a squirt of WD40 into air tools which seem to not to be working 100%.

Obviously though common sense needs to be employed with any form or lubricant or oil that's used in air tools within a paint shop, and its a good idea to let the tool that has been lubricated to free run for a while outside the shop, to ensure no lubricant/oil gets onto anything being painted.

Unless you have dedicated air line only used for air tools, which will never be used for spray guns, use of auto oilers is not a good idea, as paintwork will certainly get contaminated with oil finding its way into spray guns.

Best way to lube air tools is a a couple of drops of air tool oil directly into the intake fitting before use, making sure to free run and purge the tool of oil outside, if its being used in a paint shop.

i've seen wd40 banned from sprayshops & one guy get the sack over it.
i use the cpl of drops in to the inlet,but never wd40.just airtool oil.

 

[Engineer]

As WD40 doesnt contain silicone its no more likely to affect a paint job than air tool oil. Reason for using it is to free off the impeller vanes of air tools, which might be sticky, and it seems to work very well for this.

work in a paint shop and find out.
you alway seem to be looking for a arguement

its not an argument its a fact .what do u do when the sander slows down and gets gummed up. get a replacement and bin it or free it up run as sugested out side till clear and carry on. as i said the last 2 ive bought for £10.00 each just needed flushing out and now are fine the original poster was asking how to get the sander running not the ins and outs of for and against / anyone got any better sugestions on how to free one up without stripping let me know as i would be interested

Firstly I am 100% with Jaykay here, I have seen guys in the shop where I worked threatened with dismissal after having been told NOT to use wd40 under any circumstances where a job would end up in the paintshop. Whether there's silicone in it or not, it's a no no.

Secondly:
With you having sprayed for some 30 years, I am very surprised by this comment, as it would appear you don't know what an auto oiler is or where it goes.
Just FYI, An auto oiler goes ON the airtool, there is no dedicated airline.

It all depends what type of lubricator you have, yes there are the type which fit immediately behind the air tool, but in workplaces where air tools are used in large numbers we usually have them in the system to feed them all.
slan go fol

But in a bodyshop, they're only ever attached to the airtool.

can I just say this is getting pathetic. I meerly pointed out that to assist in getting an air motor whatever it's fitted to running free and to combat stickieness caused by MOISTURE then a squirt of WD40 wouls displace the said moisture AND provide lube while you get it running. I never suggested useing WD40 INSTEAD OF air tool oil!
Also speaking of "know it alls" I meerly corrected a statement made that WD40 contained silicon BECAUSE IT DOESN'T.
For goodness sake you think think I'd suggested drinking it or injecting it into a vien! just grow up and accept that different people prefer different ways and that those who work with spraying will use their own tried and tested methods. After all at aroung £1K + it's a lot of money to mess up a paint job, better safe than than doing it again eh!
I'll crawl back under one of our minibusses now

WD40 works perfectly for freeing off sticky air tools, but I can see why that those who are unaware of the fact that it doesnt contain silicone, would be suggesting not to use it anywhere near paint.

 

[jaykay]

ignorance is bliss

 

[danelectro]

With you having spent the last 30 years spraying, I thought you'd have been very aware of the issues caused by using WD40 in a paintshop environment. But to be honest I'm not exactly sure of your background, as you seem to know everything about everything. All I hope is people looking for advice regarding spraying and prep work do not take any notice of your advice.

I'm not sure why people have to argue the toss about something that is a fact, I always thought that WD40 contained silicone, according to the FACTS, it doesn't so I stand to be corrected. So Mr Engineer (with your apparent unlimited knowledge), what is in WD40 that causes issues with paint?

It must be, cos it was you who quoted WD40 contains silicone. As i said it doesn't.
Apparently it's light lube oil with a moisture displacer. Don't know what that is it's probably millions of molecules with floor cloths wiping away like billiow lol...

 

[drivewasher]

Thinking about it if you spray WD40 onto water it pushes the water to one side in globules, I wonder if thats what it does to wet paint hence the belife that its silicone?

 

[jaykay]

it does just that,i.e fisheye.
the problem with is it takes days to clear it from a paint shop.

 

[jaykay]

any way i've no more to say.

think it's a wind-up by a certain party.

 

[drivewasher]

Well I never! problem solved keep it away from paint shops
