Yes nice repair there, what size sheet have you used? did you double it up to give the thickness required, as the fairings look like they have a raised and thicker outside edge. Have re-done a few horrific repairs myself, and got this very same one to do when the weather gets a bit warmer.

I use 3mm thickness.
The main reason is that the overall thickness is 6mm, but the overlap/fixing points are 3mm thick.
Happy to make up an inspection corner replacement section for you if you want?, just let me know which side you need. (Or send me your fairing).
Cheers

eg for the thickness reinforcing pad at mount - what/how did you bond it - products ?
eg for cutting - use a slicing disk or jigsaw or hacksaw -tools ?
to copy one thing is plagiarism - to copy two things is called research

Hi Danny,
All very low tech I am afraid.
Sheet is covered in masking tape and marked up.
Basic shape is cut by scoring a straight line along one edge of the shape with a Stanley blade, then flexed to snap off the waste. Cutting discs generate too much heat and distort the sheet. Hacksaws, jigsaws are messy and need too much reworking to obtain a straight edge.
This is repeated until the basic outline remains, finishing is completed with sandpaper (by hand). I found 120 grit the most effective for removing material and giving a nice finish to the edge of the material.
Bonding is done initially with a thin coat of solvent adhesive, multiple points are melted through and the edges are bonded using a soldering iron then finished with sandpaper.
I will dig out some "work in progress " photos and post them.
Cheers
