I did the 16 hour course when I had my previous Kitfox (it was E-LSA). I took it at OSH during the winter.
The course is VERY remedial. There were a few things that I took away, making it not a total waste, but, be prepared to be bored out of your mind most of the time. Like Joey said, most of the information you can readily find on the web or you already know. My instructor was a very knowledgeable IA, but had no clue about 2-strokes or Rotax engines in general and spent some time bad mouthing them until he was challenged. This was back in 2009 or 2010.
STOL Demos will be Monday, Tuesday, Thursday and Friday evenings at the ultralight field. We will be camping across the street from the ultralight barn. God willing, the Mangy will be parked at the Ultralight Field. Our party is scheduled for Thursday afternoon at our campsite, details to follow.
Trent and I are in contact on this project. He has one product on his to test I have another. I’m using Herculiner with mixed results. I believe my problem is poor prep before coating. More to come this summer. Spot repairs probably won’t work. You will need to coat the entire casing to get even balanced use.
