Good finds!
There definitely is a difference between wd40 and gt85 not just in the PTFE but the way they act when sprayed, GT85 almost seems to be boiling in the surface and creeps better? Purely from a visual standpoint.

 

Pardon our interruption...

Mine turned up with extra size tins

 

I have tried pocket rocket and dw40 in the past and have stuck with gt85 for bike stuff as its just better all round. ....... never had a ktm fastener go rusty using gt85.

If memory serves, pocket rocket smells really unpleasant.

As an alternative to gt85 l'll use morris md4 - same qualities as gt85, just heavier, like duck oil.

400ml is the general size for gt85, but they do do the larger ones sometimes.

I'm going to have to have a think about why I even buy WD40 anyway...
I use ACF-50 for protection, and various oils & greases for lubrication.

I think the main thing I use WD40 for is cleaning/degreasing, for my chain & rear wheel, and occasionally to remove any glue left by labels or wheel weights.
The principle ingredient of WD40 is Kerosene (and other Paraffin oils).

You can buy 5L of Kerosene for £18 delivered, might even be able to buy it cheaper locally.

Pardon our interruption...

 

Duck Oil is good and cheaper than WD40.

 

Where?

WD40 5L can be had for £37 delivered, which is expensive to me as the first one I bought was about £12 and the last was about £22.

Duck Oil looks to be around the £40 delivered.

 

I admit I've had the current 5L can a while. Maybe I should have said it WAS cheaper?

 

Well, as a yoof, l used to use parafin mixed and a splash of engine oil as a general 'WD40' type brush on and nothing sinister happened ........

 

and nothing sinister happened ........

Now I'm a little worried, maybe something sinister did happen and you're just not telling me.

 

Duck oil is very cheap if you nick it from work

 

Ahoy, did you know that GT85 no longer contains PTFE? And here's me just getting into it.
I assume the formula has changed.
As per GT-85 Bike Lubricant 400ml | Halfords UK
Removal of PTFE

As of January 2024, this product will no longer contain Teflon (PTFE). The product performance remains the same. Older stock will still contain Teflon and this is marked by the "with PTFE" badge on the front of the product.

 

Looking at the MSDS for GT85, it is Naphtha based with some light mineral oil added, which would explains why it acts differently to WD40. The Naphtha will flash off quicker to leave the mineral oil behind.

So..as it now doesn't have any PTFE in, it is it still worth buying?

 

Probably not, that’s what made it different, why I used both WD and GT for different things

 

Was it worth buying before?

Use acf50 a couple of times a year on 3-4 bikes and 1L lasts years. Also works as penetrating oil, black plastic shiner, removing chain lube from wheels etc

Compressor essential for full coverage and not applying too much.

 

I don't think I've ever bought any, and I'll probably not replace my WD40 either when that runs out.

I clean my rear wheel after most rides so I just need something for that. I have a strong water based degreaser for around the front sprocket area (which works great) but I'm cautious about using that on those lovely anodized rims. I prefer to use an oil based solvent there instead.

 

Scottoil FS365 might work well for you.

After any grubby ride on my road bike I give it a quick hose down, followed by FS365 while wet. Generally looks great when it dries and if not, a bit more FS365 and a wipe makes it shiny.

 

Lighter fluid works well, naphtha.

 

Works well on my bikes IRL. My 9 year old 1190 has zero corrosion and has been used through several winters, salt and all. It's bright and shiny and looks more or less like when it was new.

But after the FS365 treatment I put it in the garage and don't leave it out in the rain. It's not like ACF50 which I put on a new GSA and then pretty much left it for 3 years until I sold it (perfect under the filthy gloop). You need to apply regularly., but a quick rinse and spray only takes 10 minutes.

Yup, that's what I worked out and why I decided it wasn't suitable for my extremely damp garage.
Also when touring my 1190 has been left outside in the rain over night (on a few occasions now) and still looks mint thanks mainly (I think) to regular ACF50 treatments.

 

Bad news on the GT85 front - all my stock is from a bulk buy a couple of yrs back ....... l'll buy a can of the woke stuff and see if its any cop.

Oh, IME, Fluid Film/Lanoguard is stacks better than ACF50 (but l like the grease for 'lectrics)

If the new GT85 is pants, it'll be MD4.

 

I have emailed GT85 direct ....... just to double check. Will report back if they reply.

Why oh why do manufacturers have to mess with stuff.

 

On a related theme - does anyone have a known safe method for fitting a shraeder valve to a used aerosol ...... so you can make your own spray can (if buying a 5 litre tub of product)?

 

Yeh, I've made several of them now.

These are the best valves I've found, though any valve can be used.

Pardon our interruption...

This guy shows the method pretty well.

I drill mine, if you do then be really careful when drilling the can because if you nick the straw inside, it won't work.
Also I use a blow torch to solder them in because I don't have a soldering iron that big.

 

Brilliant - thank you for that ...... better get 'soddering' ....... make an MD4 aerosol 👍🏻

 

 

Project farm did a very good review of similar, l'll see if l can find it. If memory serves, Steve has posted before.

 

Xcp clear coat seems to be a good better than acf50. Interesting to see

 

😵‍💫

 

Car based and american, but, still of interest imo.

I have beèn using lanolin products for a while now on 4 wheelers and its good stuff - just using some now on a bike over winter (started using lanoguard, but also trying fluid film out of curiosity after seeing this)
