I used poly-tone on the fabric and aerthane on the rest. I completed the aircraft 14 months ago. The poly is holding up fine but i only clean with soap and water; it will not hold up to chemicals. Fuel is fine on the poly but dont get raw fuel on white cause it stains.
Per the poly-tone rep, put the gallon of paint in the refridgerator the night before and it will shine more. Thats what i did and with a couple coats of ReJex wax i think i have a semi gloss.
