I too was experiencing PFSD, or pre fibreglass stress disorder. It is curable.
Read and reread those instructions. Spend some quality time on YouTube watching fibreglass tutorials until you feel you can do it in your head, then have at it. It's a lot easier than it sounds to the inexperienced. The canopy project is a bit daunting, but if you follow the directions, it is fairly straight forward.
This is where you get to put your own touch to your project. You will feel ten feet tall and bulletproof when you gaze at the beautiful flowing lines of the canopy fairing you created from a bunch of resin and stuff.
Go for it. It's really only plastic after all. Forgiving stuff on rework, and a good skill to develop.
For me, the hard part is knowing when enough is enough. You can work endlessly towards perfection, or stop when you think you are close enough.
Hope you find this helpful
