i used felt to cover the window guides as my original ones were scratching the window.

i hot glued them to the metal then hot glued another layer for added cushion.

is this a good solution or should i get the right ones from the store?

Probably just as good as the OEM style, though you really aren't gaining anything by stacking two of 'em.

that should be fine since thats what the original ones are they had felt on the ends to press against the glass
