Although I could find replacements (not painted, like the original), I recently painted the inserts in my SH49 topcase.
One side had deep scratches in the plastic... Not having any plastic filler at hand, I used the superglue/baking soda method to fill them... Sand down and 5 light coats of "paint" later (1 primer + 2 paint + 2 satin varnish), I think the result ended up pretty good...
