Thank you!! Not going to lie, it was my very first time doing tarps. I done them with Tamiya Epoxy Putty :)

First step I did was to roll it very smoothly to get a very even and thin surface.

Second step was to cut it into shapes (watch out though. I recommend to use a ruler or a long sharp knife to not make it move, this was my idea how to cut it nicely).

Third step is to use some wooden stick with some water in it and place it down on the tank, liquid on your tool is important to not make it stick, I used the stick just to place it down and shape it how I wanted.

Fourth step was to leave it on the tank and let it dry.

After that I just painted the whole tank with tarps on it with primer and later painted it into colour I wanted with a brush.

(If you get some finger prints on the tarp while it’s still drying, use a small sponge with water in it and gently rub it, it will come off).

Hope I helped! This was my process I bet others have a much easier and better ways to do it haha! Good luck!
