My son and I made a skateboard ramp from 2x4s and cheap plywood.
It will be stored outside and needs to survive for 2-3 years.
This is definitely a "cheap" product, I just do not want it to rot or plywood to delaminate prematurely.
We already stained this ramp with minwax oil stain.
Do I need to apply sealer on top of minwax?
If so, which one? Also oil based?
thanks
