No. 5 Rubber Buttpad Renewal

FWIW, an automotive product called AT-205 Re-Seal does a magic job of renewing the rubber buttpad of No. 5s.

I've used this product on my vehicles for years (originally suggested on Youtube by Scotty Kilmer, auto mechanic for more than half a century and former CBS resident auto expert) with excellent results on rubber(ish) boots, engine mounts, and a lot more.

The original buttpad on my nearly unused No. 5 Mk I was kinda clapped out just from storage. A couple years ago I replaced it with an NOS buttpad from Apex and have been very happy with it. (Still kicks like a mule, but I digress.) I applied AT-205 at the time and it looks "better than new" by my standards. Certainly looks better than when unboxed.

Last year I decided to apply it to the original buttpad. Now it too looks almost new, aside from some cuts and missing small chunks.

AT-205 does not come with instructions. I apply liberally with a folded paper towel or clean rag and give it an hour or so to soak into the rubber. I applied three fairly thick coats, all of which soaked in so I have the look and protection I want. I let the last coat soak in overnight. Note the rubber will be somewhat sticky until the AT soaks in; afterwards no stickiness at all.

Not a biggie; hopefully helpful to a few.

What does this stuff actually do?

I've used Gummi Pfledge rubber treatment on mine, which has been excellent.

ATP Automotive AT-205 Re-Seal

Used it quite a bit in vehicles. It can do the trick for older seals in engine and transmissions when you aren't ready for a proper tear down.

Also for vehicle external rubber(like) parts. It's a polymer rubber rejuvenator to extend life of the item.

I've used Simple Green at 100% with some success, but IIRC the YT vids I watched showed there were more complex but probably more effective methods that used other ingredients as well.
