I only cover with the Ultra but I do use the Mono for trim sometimes. I juice up my window cleaner with more ammonia for that added kick. After the trim has set for a day or two I use my trin iron set on high and run it over the edges of the trim, about 1.4 inch. I like using this method because you can slide the trim around and get it right where you want it. Thanks for bringing that tip up CW. I was back tracking on this thread and looking at some very nice planes. Tony, when Brian finishes his build and I get a copy of the templates I will be making up some copies and if anyone needs them I will be happy to send out a few sets. The plans and instructions tell you what each part is made out of, you will have to do your own figuring though. I buy my wood in bulk from Lone Star Balsa ans I can cut {my own} kits and build several of these planes for next to nothing. The money starts to mount up when you need to order cowls, canopy, LG and hardware. Back track on this thread and you will see how much money you will spend on stuff other then wood. Wood is the cheap part.
