Im really confused about these raincovers.

I now have mine fully undersealed, inner sills protected, etc so should be rust proof, and was wanting to get a raincover for the winter periods.

The car can be under a cover, but still exposed to the elements.

But I dont get it.

some people say it causes paint bubbling

(like Q, and another member had his front arches go), others say it scratches the paintwork etc.

Is it actually better just to load up on wax and leave it outside bare?
