I've used aluminium heat tape to attach it to the fairing. So far it's stayed put. I did that as it could be removed. But on my other fairing, I've fibreglassed the grill to the fairing. It's obviously stronger but the downside is it's permanent (unless I cut it out). Can't see what I'd need to though and if I was painting the fairing again I would just mask it off.How did you attach the mesh in your tail holes please?
I'm tempted to do the front grill in the nose too.
