Wheels i have used
marine ply and
oregon,had it treated at twice the below ground rate for the last 20 odd years and had no problems with gluing it ,i saw a
boat i rebuilt 20 years ago and and the treated ply
cabin was as good as the day i built it.The
epoxy glues we have today
work great ,the one draw back that treated timber has is getting
paint to stay stuck to it but a coat of everdure fixes that.
