I moulded the mesh around the piece then marked a uniform depth for cutting. I used a few bits of PTFE as a spacer and a fine tipped marker to keep the same distance. Once marked on the masking tape, I cut the excess with tin snips. This was repeated for all 3 holes (Oil cooler area, 2x brake ducts)
The mesh was then stuck onto to the bodyshell using some black CT-1. I tied some thin string through the mesh and pulled it forwards to keep some tension until the CT-1 cured.
