Tru oil warranty?

[Strat Avenger]

I used Tru-Oil on the back of my Warmoth maple neck (which feels great). After the oil cured, gun stock wax was applied. The fretboard and headstock face was sprayed with a urethane satin clear.
That was 5 years ago and I have never had a problem.
The neck has remained stable and hasn't even needed any seasonal truss rod adjustments.
