heatshieldstore.com makes custom fit window covers that are both heat reflective and black out. they offer them for the GX470. weather tech makes a similar product for the GX460 (without suction cups).
these units use suction cups and there are small light gaps.
the build is OEM quality in my opinion. there are some light gaps, but this is probably to be expected. the rear passenger (middle row) covers have some areas where you might not want to jam the covers into the crevices because the window split framing makes for less room to cram the covers.
pictures tell a thousand words.
above is the rear windscreen. you can cram some of the window cover in some areas.
