Plywood is not durable in the long run. It will crack like the plastic and it can mold, too. Stop buying cheap plastic crap and get either thick high-quality rubber or steel pads. No Harbor Freight crap, ok?

That's basically a T or Y connector with an in-line flow control valve. There probably are kits for that. Make sure you have everything sized correctly. Be wary of US vs metric sizes and units as swapping between the two can lead to leaks due to tiny size differences. Make sure the valves are all one-way flow, too. Pic related is roughly how it goes together.

Or you could just mixt it together ahead of time and use it combined in your sprayer. That should work most of the time, too.
