yeah, if it's on the deck, clean the wax really really good... like not a trace... and then when they wax over it again, it will be locked in & last a long time!
Somewhere I have a 3 year old post of some flames I put on my grandsons board & that lasted years on 3651!
If it's for the bottom too, it won't last as long because there will be no wax to protect it.
