Ditto.

Balsa is MUCH easier to repair or fix.

I have mounted DOTS in cowls when there was no other choice, and use the technique of first applying CA on the cowl to harden the entire area.

Then after a light sanding I EPOXY a hardwood backplate where the DOT goes, and finally a large washer behind the DOT to spread out the stress.

This has worked fine, but I avoid doing this whenever I can.
