The "over" section is missing "high nitro fuel".

The problem with electric is that once you get the smoke generator and sound system installed, the plane is too heavy.

Aero Gloss works over K&B Superpoxy (for all of you planning to finish your airplane in 1975).

I think Harry Higley should be given credit for this chart as it is from one of his books.

Don't know how old this chart is, but if its more then 5-6 years old then it may not be all that accurate. EPA and some state regulations have forced formulation changes in some products. Some stuff I've used with success in the past is nolonger compatable, so still make sure you do a little test before commiting.

   I think this is a far bigger problem than mixing types of materials. Dope can very frequently be incompatible with itself from batch to batch. I feel pretty comfortable with epoxy being consistent, at least with the sprayed material. The thinners are generally not compatible, but my most recent airplane has a mix of Klass-Kote, ancient K&B Superpoxy, and even more ancient Hobbypoxy, and even mixing the Klass-kote with half Klass-kote and half K&B Superpoxy catalyst (to get the correct shade of brownish white, I used the catalyst from a rusty can!) seems to be fine, just like Dave Platt said it would.
