I support your Guinness recommendation.....no MSDS sheet required! Well done, Thanks Jon.

Good delivery of knowledge. Excellent choice of beverage too !

Hi Jon. Thank you for a very useful video. I didn’t realise that the solution could be reused. I will check out the product you use and compare it with what I’ve been using. Many thanks. 👏👏👍😀

👍👍👍👍👍👍👍Worth making video and showing us Jon. Well done. Regards from Australia.

Cheers Jon, another interesting video. I've had mixed results with HyBlack from youplate. From what you've said I think inadequate degreasing may be my problem. They sell the solution in small quantities, so not as big an outlay for just experimenting with. Steam / rust bluing is also on my to-do list, but that list only ever gets longer!

Good morning Jon, excellent video! Great timing, i am just in the process of making a lot of tooling for my flypress (punches/dies etc. This will be a perfect solution to stopping the surface rust while on the storage shelf in between uses! Thank you Jon. Regards Tony.

I think a safety sheet should come with the Guinness too. I have seen too many friends make mistakes after consuming copious amounts. Especially at closing time of the bar. LOL!

good video Jon..thanks for your time

Having done quite a bit of Blacking myself I can only agree totally with you. It really does protect as you say. Although I do have a toolholder with a great big finger print on it. Oops. Regards. Steve.

Gday Jon, great video, I’ve never been a fan of the look of blacken tools, I prefer the shiny look but here I don’t have much issue with corrosion thankfully, the product you use certainly works well, top job mate and make sure you keep the blacking solution up to the stomach lining, cheers

Thanks for a good video, very useful. Didn't realise that these fluids could be kept for repeated use. Might be time to buy some...... Laurie.

Cheers Jon, Good one ! One precaution on anything that's been chemically blued or color case hardened.... Evaporust or similar products will remove the coloring, since it's a form of rust. Found out the hard way.... ATB......

Thanks Jon, good information 👍. Guinness is a helpful compound. 😁

Good video Jon.

I use a very similar product from Frost's. I have been throwing it away after one use. I will now try reusing and see how it goes, thanks for this tip. 👍😎

Hi Jon. I got some cold blue that I need to try out. I suppose your method using the meths means you can always sneak a cheeky extra shot into the Guinness! 😂

Hi Jon, just saw the price! I use potassium nitrate, aka salt petre, melted in steel container and get a nice deep blue, cheap here in Philippines but probably on the naughty list of chemicals in UK. As an apprentice 50 years ago we used it for blueing our projects.

Drink that Guinness John! You cant leave it standing for too long. I can't afford it in Thailand It's about 8 quid a pint.

Excellent video. I'm with you Jon, and prefer chemical cold bluing. I use Phillips cold Blue, 1:3 mix. The bottle does have all the warnings on the bottle. Very harmful chemical. I wear rubber gloves and safety glasses and a face mask. Although I admit I didn't wear the mask in my video so I could talk about it, but that's the only time. Promise. Cheers Nobby

Hi Jon, when I first saw the Guinness I wondered if the level would go down during the video. I have done a lot of hot bluing over the years (e.g. heating the items with a torch then quenching in oil). That works great and the main reason I did not use cold bluing solutions is that they are so expensive in NZ. But, I recently found a 1 liter bottle of Birchwood Casey Perma Blue Liquid for a really good price so I brought it. I presume it is similar to the product you use. I have used it on a few parts and it does make a good finish so I am happy with it. Yes, it is really strange that your bottle does not have and warning labels on it.

Thx for the vid.

Well,,, that was well timed😊 Ive been given a Perfecto lathe and intend restoring it. Lots of parts that are rusted and need re-blacking. Was thinking of going down the hydrogen peroxide and boiling route but i think I'll follow you down your path. Nicely done Jon !! Cheers Neil

Hi Jon,…I will try the re-using of the chemicals.Always used new stuff for some reason.I never seem to get a good result on threaded areas must be the cleaning or lack of it😅

well no I do not drink alcohol however I could drink a Guinness Dark Stout i'm time to time and very much enjoy it. I will on occasion have a shot of whiskey nate but for the most part I don't drink but I can't appreciate that fine Dark stout. great video Thank you for sharing. it looks like maybe we need to exchange stickers I have I have one of yours. but I do not believe you have one of my stickers good days cheers Kimber

Go on , try dunking them in Guinness ! 👍👍👍

Hi Jon, you are absolutely correct that the product should carry the GHS chemical hazard symbols that are on the safety data sheet (SDS]. If not Caswell are in breach of the GB Classification Labelling & Packaging regulations. You can report this through your local Trading Standards Office. I would have tried their products but unless they get their act together I’ll avoid them.

You didn’t tell us that it costs 80 quid for a litre.. the instructions are readily available online. Stavros

Ay up Jon, any chance you have a link for the best place to get this stuff from please? Tony

Do they also use the same product to blacken your Guinness?
