The front air dam is mounted with about 8 steel 90˚ brackets screwed into the bottom edge of the bumper. The plastic trim is drlled and attached with one 8-32 pan head stainless machine screw and nut/lock washer per bracket.

I will take a look at Home Despot next time I'm here to find the product name.

The coroplast side skirts are cut and assembled just like a cardboard box. To bend cleanly, across the grain, you just have to crease the inside of the bend with the end of a stiff steel ruler. Press it down in stages, overlapping each indent by half, then bend up.

To bend with the grain I used the end of my Olfa knife to crease the inside of the bend line with the coro on the floor, straddling the crease line. Push the rounded end into the line and pull towards you, following the "grain". That way the plastic will bend inwards towards the crushed part of the coro.

Instead of taping the coro together you could use pop rivets with tight fitting washers on both sides.
