Hi,
I did it with acrylic at the time, but now i don't do it that way. I use acrylic only when client wants as cheap as possible and only for inside. Normally i do it with 2 component industrial polyurethane when for outside.

I don't use that V bit anymore. Instead i use CMT 90 degree insert V bit. For 60 degree i use the pyramid 6mm bits from China, Aliexpress.
