Fibre glass work and trimming steps for wheel pants?

Sitting in a snowbank here in Canada and thinking its time to put my new Vans RV Pressure Recovery pants onto my RV4

I have the pants, hardware and the drawing DWG C2 from Vans Main Wheel Fairing Installation dated 2/17/99 so almost ready.

The fibre glass work will be new for the most part. Anything I had done last was snowmobile repairs in the 70’s and the 80’s

Is there anything that is more step by step on the fibre glass work and trimming for the wheel pants?

Thanks

Tim
