It also looks like it needs some fuel proofing on the ends of the square stock protruding past the firewall.

The original Super Kaos Jr. plans did not have a full belly pan under the wing. I bought a copy of the RCM plans this last July. Was debating about purchasing this arf. Bought a Bridiairplanes Utter Chaos for $65.00. "Money-kote" at the LHS is $20.00 a roll. Might need three rolls if I want a choice of colours. The price of the arf is looking a like a better investment. By the time i'm done with engine mount, fuel tank, and covering it should run me about $170.00 CAD to complete. The tower koas might run me with shipping, Canadian 7% pst (provincial sales tax) and 7% gst (goods & services tax) about $150.00. Yes our health care is free, but we pay for it in other ways.
