Looks nice, congrats, I would pick up some sun-shades
The aviation catalogs sell the plug material "kits. Each contains a square section of yellow plug material along with the cords and stuff for DIY. They cost ~$20 but are the right stuff for the job.
BTW...another idea...
I know some guys who stuff loosely woven plastic scrubbing pads into their Cessna's wing air inlets and leave them there. They claim it doesn't reduce the airflow and keeps bugs, spiders, wasps, etc. at bay.
I'll give it a shot! Thanks!
