hey man i recentlly went into my local hobby shop and asked the man who owns it what was his prices on clearcoat,he told me i could buy the expensive clearcoat or i could use future floor polish he said it won"t turn yellow and last a whole lot longer than clearcoat, and alot cheaper,he told me to mix 2 parts future and 1 part 90%alcohol and always clean up afterwards,anyway i have sprayed all my models and they look great,so good luck man let me know how they turn out
