Compatibilty of slide rings sealants with immersion oil

This is about ringing with a single sealant, that serves for sealing, protection of the resin layer from humidity and alcohols and immersion oil, and provides am esthetic appearance as much as practicable.
As described in a previous post, ringing slides with nail polish (NP) by means of the DIY ("short-term rotation") ringing table worked for me. It is equally convenient for other lacquers and paints.
However, I was annoyed to find that the NP rings were not compatible with immersion oil. Namely, immersion oil, upon long-term contact (say, an hour) with the ring dissolved it and caused swelling. Is this a new finding ??? this happened even when the oil drop was laid on the ring several days after ringing; the NP layer must have been dry for all practical purposes.
Naturally, the specific NP brand was suspected. So I tried it with three other brands as well, and got the same result more or less.
An extensive test is planned, on as many brands of NP that I can gather around.
A shellac ring was destroyed by the oil.
Model paints, Revell and Humbrol, also failed upon several hours exposure to immersion oil.
So I tried Hammerite, a "direct on rust" white oil-based paint. Placed an oil drop on it two days after ringing. So far, an exposure of 10 hours did not harm the ring.
Note: I am using Cargille immersion oil type A, bought less than a year ago.
