I am going to be installing quite a lot of 1/2 round flog roll garden edging.
It comes pressure treated .... but want to give it some more help.

Thinking of dipping each roll for an hour in a solvent based wood preserver .... as that stuff soaks in well.

Years ago I used to use Cuprinol preserver. That had consistency of paraffin ...and was green in colour.

Dont know if that is still available .... but be good to know recommendations of suitable product.

Creosote is the only good one now. It kills plants of course.
Cuprinol was copper powder in oil, hence the name. I daresay the original formula could be made fairly easily, but it requires very frequent stirring in use.
