Solar oil used on any system Fibreglass/Silk or L&P will keep it plasticized......even Gel likes it lol........
it will prevent curling of the natural nail as it is getting his daily TLC, will keep the coating in tip top condition and the natural nail will get a daily dose of TLC too......
Solar Oil is great no matter who's enhancement products you are using, it does not discriminate........ Acrylic loves to be oiled, ex-specially if the oil has such tiny molecules that it will just get the the heart of the matter.......
Just think if you have a rubber band and just leave it out and exposed to all sorts of weather, sun, rain and the like it will get crumbly.... but oil this rubber band and then expose it to the elements and it will stay supple and springy for so much longer......
Expose any type of Enhancements to the elements of bath water, dish water, house hold cleaning chores and it will go the same way over a period of time...... so Solar oiling is in my view a must and I advise my clients accordingly, specially my Fibreglass and silk clients.......as resin tends to break down in water much faster then L&P......
