Looks to be the Mercedes-Benz M111 valve cover. Not a fan of music backgrounds. Would rather hear about life challenges, your opinions or your mum. Great video!

[@THEOGGUNSHOW]

Beautiful outcome 👌 🎉😊

[@gafrers]

Thanks for the honesty

[@senatorchinchilla5389]

It won't catch fire from just water, but if its already on fire water will speed it up instead of putting it out.

[@2fwelding842]

Depends whats chemical dip. If its acidic, yes it will react. Some more aggressive than others. But companys offer both options usually.

[@GMPC]

Great job as always

[@UniqueCoatings]

Thanks

@@UniqueCoatings what is the stripper called mate, great videos

[@darrentopham8165]

Hello mate. Was the underside of the valve cover as corroded as the top was ? Im just wondering whether if it wasn't as pitted that maybe it was the blasting media that caused the damage not the acid. Just a thought. But great video either way

[@UniqueCoatings]

Wasn't the blast media, blasted magnesium for different purposes before and never had anything like this. Thanks for the suggestion though buddy its appreciated.

[@kristianirvine4192]

Great video very informative Mick. Did you have to chemical strip could you not just of media blast it ?

[@UniqueCoatings]

Media blasting isn't sufficient to remove previous coatings. It would of taken days to blast off and a lot of waste media.

[@kristianirvine4192]

@@UniqueCoatings thanks for the reply Mick very helpful .

[@richardried4197]

What is that chemical stripper? Where do you source it from?

[@bluezguitar1]

Thanks for the informative video. -- Until a week ago I had no idea working with magnesium is so problematic! I'm thinking of powder coating my 98 SLK230 valve cover, which coincidentally is this very part. Apparently MB has discontinued making it. Anyhow, I'm more concerned with longevity than aesthetics. Do you think this valve cover is still functionally sound after the powder coating?

[@Koenigsegg1115]

I don't think this is going to last long. If you don't seal the inner side of the valve cover, you're always going to have oil penetration through the magnesium creating oil bubbles under your paint. I have the same issue on my r170 230 and I was thinking to seal the inner side with gluptal paint but it is very difficult and expensive to find in Europe. Good luck with it

[@bluezguitar1]

@@Koenigsegg1115 Thanks.

[@hggryrdchgc]

I didnt understand why you wouldnt do it again. What affected the overall quality?

[@leecherone7601]

I have a magnesium alloy bike frame that I’m hoping to re paint. Not sure if it’s powder coated or painted? Any way I can tell and would you just recommend sanding by hand and respray with paint? Also, who are the bands you used in the video, sound great!

[@UniqueCoatings]

Strip it by hand, don't drop it into any sort of stripping chemical and it will be fine

[@JohnWD40TC02]

Should be a good one Mick 👍 shared these in my usual FB groups, see you later 😎😇

[@UniqueCoatings]

Thanks John, appreciated!

[@JohnWD40TC02]

No problem Mick, bill is in the post as usual! all reet 👍😂

[@UniqueCoatings]

Orate John cheers buddy 😅

[@JohnWD40TC02]

Really really sorry Mick but I totally forgot about this, my memory is getting bad these days and it makes me so frustrated when I forget things like this, I'll watch it tomorrow. Sorry again 😠🤞👍

[@UniqueCoatings]

It's no problem at all John. I'll try for Friday next week and then you have no excuse 😉

[@JohnWD40TC02]

Finally got round to watching this Mick and I'm very disappointed as I thought everything you read online wasn't true but they were right here, the problem is everyone said my painting was crap so you mean to say it's all true! 😨😭🤣 Sorry I missed the live chat mate but I'm blaming Tony for not doing his on Friday as it totally ruined my weekend and left me in a state of utter confusion, tbf though it doesn't take a lot these days 😁😂

[@UniqueCoatings]

It's fine John! I'm sure your painting isn't that bad! I'll aim for Friday this week... I'm happy blaming Tony for the confusion though 😁

[@JohnWD40TC02]

@@UniqueCoatings 😂😂🤣🤣👏👏👍👍

[@heymadam]

I've read that media blasting magnesium introduces "impurities" into magnesium. Is this true?

[@UniqueCoatings]

don't blast it hard. low pressure and fine media

[@bikerbrego]

I’m just getting started at home powder coating. I’m going to try it on my dads C3 corvette that I got from him. What chemicals did you use to strip the old coatings ?

[@UniqueCoatings]

Hydrofloric acid. I wouldn't recommend using it at home though.

[@bikerbrego]

@@UniqueCoatings thank you. Great video’s

[@UniqueCoatings]

Thank you. Any advice needed to help you from home just ask!

Thank you!

[@rossbrannigan3273]

Interesting experiment! I have some 1960s Italian magnesium engine castings that need refinishing. Some points I've discovered: magnesium is very different chemically to aluminium. The myth about water setting fire to Mg???? No, you're right - that's not true but Mg is flammable itself. Get a thin bit and light it and it burns with a very bright white light and extreme heat. Water will not put it out but will instead instantly vapourise with an explosion - extremely dangerous. My chemistry teacher showed us this in class on a tiny bit of Mg. Mg castings will corrode over a long period of time with dampness - which will begin instantly. Corrosion will continue under the powder coating because it does not need oxygen to continue - so you need to "passivate" the Mg. Dow used to do a pickling treatment but it is now banned in most places as carcinogenic. There are safe paints that helicopter repair places use now.

[@simonwhite326]

Who's chemical stripper do you use?

[@UniqueCoatings]

Ribble technology.

[@jeremyhaddix9561]

Can you still out gas magnism for a long time

[@UniqueCoatings]

Yes

[@medievilassassin]

Could you not have put filler in the bigger imperfections?

[@UniqueCoatings]

I could of done, but as a business I'm not going to waste materials and time on a cover that is now scrap 😉

[@UniqueCoatings]

As said in the video, the customer wanted me to go ahead with the process. Also I said in the video the acid had eaten into it affecting the quality of the cover and the finish.

[@MrRedcelica]

ive powder coated many mercedes engine covers use a spray or paint on stripper and the casting is never perfect anyways, paint doesnt stick to magnesium well, pwder coating is best!!

[@modenaro1776]

Rotax has been powder coating their Mag. motorcycle engines since the early 1980's. Who ever said it was not safe? Never heard that till today. Here.

[@deanbrown7643]

👍👍👍👍👍👍👍

[@deanbrown7643]

Mick you did what the customer asked for regardless of your reservations it's now far far better than it was ☺☺

[@decanes4218]

I powder coat Magnesium a lot but don't acid dip it. I have done close to 1,000 pieces but are all flat and just sand them

[@araboharabedian]

What about over the counter aircraft paint removers ?
