My first Oratex experience

The smallest part to cover, other than the landing gear, is the rudder so I started with that. Both the frame and the fabric (where it touches the frame) need to be prepared by applying the hot-melt glue. I'm normally very sensitive to smells but when painting the frame and fabric I couldn't smell anything. I had to put my nose in the bucket to feel a slight sweet smell of "children glue". 
The hot-melt attaches easily to the fabric but I had to lightly sand the frame as the epoxy powder paint is very glossy. I let it dry over night (small surfaces can be dried rapidly with a hot air gun set to cold). The synthetic brush is easily cleaned in water.
I clamped the fabric to the frame, making sure it was positioned so that the hot-melt on the fabric was correctly aligned to the frame. While attaching it with the iron at strategic points, I did apply some moderate tension. Using the hot air gun when covering any rounded surfaces helps to soften the fabric and make it fit easily before using the iron to activate the hot-melt. 
While the rudder is the smallest part, it has a a long rounded edge and I had decided to put a pinked edge tape on it... Not a beginners task but you have to start somewhere. There is video on YouTube where this is done and I used a similar method. The edge tape already has hot-melt on it from the factory so it is very easy to work with. The result was not perfect but absolutely satisfying.
Final tension is applied with the iron... and then it is finished as no paint or other surface treatment is required!
I will try to do a time laps video when covering the elevator.
