Get a toothbrush and try scrubbing a bit of the crinkle paint on a discreet area with WD-40. If it leaves the paint unmolested, then WD-40 should remove the old hardened adhesive. I've done this with the crinkle paint Super 5 series and it worked great. The only paint I wouldn't use any solvent on would be the Dupont Duco glossy paints of the Corona Four and the Seedline Sterlings.

You might try some Goo-Gone...but maybe do a test under the ribbon cover to make sure the crinkle-paint likes it.

I had some old athletic tape on a smooth-paint machine that only Goo-Gone would take off.  I used a cotton pad soaked in the Goo-Gone and let it sit on top of the tape to help moisturize the old dry tape and after 1 hour or so, it started to just peel off with my fingernails
 

Hi Lazy Dog

If you are in the continental US of A, you have the best option available to you in the form of J.J. Short & Associates. They are a family run business based in Freeport, New York State and their specialty is anything to do with rubber. The work I've had them do on the platens for my typewriters is exemplary. Although the cost of having a platen re-covered may not be cheap, your little 2Y- Skyriter will be like a new machine and possibly outlast you. My 1936 Imperial Good Companion is 86 years old and with its renewed platen should last another 50+ years. Hope this gives you somewhere to start. All the best,

Sky

PS. Glad you like my signature, I first learned about Frederic S. Durbin from an eBay listing by a typewriter enthusiast who always types a page of text for one of his pictures and adds a 1 to 2 minute video of the typewriter in the listing.

Hi Once Again Lazy Dog

One thing to be vary aware of when using Max-Pro is the fumes are not pleasant to say the least. Use only in a well ventilated area (outside is best) and several light applications is better than a couple of heavy ones where the product is dripping off the platen. Just for interest, is your new Skyriter Deluxe a 5Y- or a 6-Y prefix on the serial number?

The lightweight or plastic Smith-Coronas were introduced in response to the Japanese flooding the world market with their low cost portable and travel typewriters. The trick to keeping those little chaps happy is to get them properly tuned, then always use a steady light touch when typing. Many of the typewriter repair shops despised those units as people would type on them as if they were typing on an old office machine and throw things out of adjustment. All the best,
