I tried it out a couple of months ago.. well, you tried it out for me :) I had some rubber car parts , 50 years old, that are absolutely unavailable now. They were shrunk, hard, couldn´t be used. Thanks to you they´re like new and fitted like a glove. I checked on them lately, they are still fine. THANK YOU for this priceless info !!!

Thanks for the question. No the rubber parts are not as pliable as when you first complete the process, but they are still more pliable then what they were before going through the process.
Hi Michael. Tell me if I got this right to your answer to Driver///1 question about after the swelling goes down and return back to normal size, the carb boots will still hold to their flexibility? Thank you for your video. I click this as a like and subscribe.
To be honest with you I don't know if it would work or not. Rubber compounds can vary significantly, so what may work with the softer compounds used with older motorcycle components may not be compatible with the compounds used on the soles of shoes.
Hi Driver, I can't tell you chemically what actually happens or if the plasticizers are restored, but I can tell you the physical compliance of the rubber is greatly improved and doesn't go away with the parts I have put through this process.
Great video. But all you have to do is get a bowl of water put in microwave, heat up water to almost a boil, put boots in for about 10 minutes, and your have no problem getting them on your carburetors and air box.
Hi Aaron, I would agree that using hot water or even a hair dryer is a good way to temporarily soften rubber to remove or install a rubber boot from an air box. The method I shared in my video will go a long way in restoring an rubber boot back close to its original condition, so when you go back in a week or a month it will still be easy to remove and replace. Thanks for commenting!
That works, but.. Once cooled down they will be as hard as before, if you want to restore flexability, methyl salicylate / alcohol is a way to do it. It is great to enlarge the part so you can use this method to fit another type of carb with a larger diameter. Fit the carbs before the boots shrink down again, good trick. I´ve tested brake fluid as well, that took over a forthnight, and there was no noticable swelling eighter, so these 2 methodes worked fine for me.
Why gloves ? Do you put on gloves why you rub your hands with disinfectant gel ? Because that´s what it is : isopropyl alcohol, and methyl salicylate is harmless. It is used in beverages and food, fragrances. Stop being scared of everything you don´t know. Which must be a lot..

What kind of person is out here thumbs downing a video like this??
If the swelling doesn't go down after 4 hours seek medical attention!

Nice. I wrap them in a paper towel and saturate with either Marvel Mystery OIl or PB Blaster. I don't have result as good as yours but it helps.
compliant or pliable ?
Any update? Are the rubber parts still soft and pliable? Thanks.

The swelling will go down as the solvent evaporates away.
Is it possible to apply the same method to soften up hardened rubber soles on shoes?
To be honest with you I don't know if it would work or not. Rubber compounds can vary significantly, so what may work with the softer compounds used with older motorcycle components may not be compatible with the compounds used on the soles of shoes.
Can you please tell us about the long term effects? Does it really restore the plasticisers permanently?
Hi Driver, I can't tell you chemically what actually happens or if the plasticizers are restored, but I can tell you the physical compliance of the rubber is greatly improved and doesn't go away with the parts I have put through this process.
@@michaelmineart1889 thanks for you answer.
Excellent video, thanks.
Where did you get such a large bottle of methyl salicylate?? Im trying to do the same thing with airbox/carb boots!
Hi Joseph, I purchased my metal salicylate at Amazon who sells 1000 ml bottles. Here is a link: amzn.to/2IlkMYc
Can i use ethyl alcohol instead of isopropyl?
I don't know what would happen if you used ethyl alcohol so I would only recommend using isopropyl alcohol.
Yes, works just fine too.
You can also celebrate with ethyl after softening your rubber

Great job! Thanks
It is salicylate - pronounced 'sal is silate'
👍👀
No gloves :(
