PPG Concept K-36 and other paints- Are these avilable only form radiosouth?? I tried to search the internet for dealers and some prices on K-36 and failed to find one. On RCU, I found from some other post that the K-36 is around $150/Gal?? In that case, $26 for 10oz at radiosouth may be way too expensive??

Any online sources/dealers of these primer/paints?? I may be interested in buying in bulk to paint not less than 3 to 4 planes.

Thanks
Srikar.
