I use Pledge on my machine beds when I'm quilting. It is just a dusting spray and I can't image that it would hurt decals and top coats in any manner.
another thought, is your featherweight set into a desk or surrounded by an acrylic frame? If not that may be a proportion of the problem, the difference between a flat surface and working over a hump is amazing
