We have a customer that we cut a ton of parts for that are all for interior/light exterior use. They are asking for options on a 1/4"+/- material for some parts that would be good for exterior applications. All these parts get painted but not to a level that would ever protect the substrate or even something like an exterior ply. Ive gotten pricing on 1/4" PVC sheet. 1/4" exterior MDF, FRP panel (.090" smooth but has some of the fiber strand texture), and 1/4" MDO.

Just figured I'd toss it out hoping there is something Im missing. These parts are all cut on the CNC and of course need to be in the impossible realm, thin, relatively smooth, weather resistant, and as cheap as possible. We are buying 1/4" MDF in units and will never come close to that price but as close as possible would help. Ive never bought any exterior MDF so have no idea what the 1/4" material would run as an upcharge. Our supplier only stocks it in another location so we would likely have to bring in an entire unit.

Thanks..
