Repaired the front belly pan and brake ducts. Hit a curb and broke the front belly pan and some of the plastic rivets that hold on the brake duct. Ended up with a "passable" repair and saved $330 for a new belly pan (which I would also probably break) so thought I'd pass along some pictures and tips. Replacement rivets are PN6500911 - 1/4 in black nylon (pictured) and I got 50 on ebay for $10.50. You will need a special riveter. The usual pop-rivet ones won't work. You can get a plastic riveter from Harbor Freight (pictured) for about $18.00. I also needed a plastic welder (pictured) that also came from Harbor Freight for about $20.00. The riveting is easy and the repair was quick. The plastic had bent in some places and you could see white stress lines. A heat-gun warmed the plastic and bending it back into shape made these marks disappear. Welding the crack closed was a little more challenging. What worked best for me (after trial and error) was to apply some plastic, let it cool and add a bit more until the crack was filled. That in a nutshell is how I am spending my corona lock down (so glad I'm not in Michigan!).
