Wasn't there something called EconoKote or something along those lines?
Cheaper version of MonoKote.
Has anyone tried any off-brands / cheaper ones... if so... how well does it work?
Econokote is essentially monokote just thinner and therefore cheaper (even made by the same company). monokote is for the gas guys that build from balsa and depend on the strength of the covering (monokote) to make their airfoil. us foam guys are looking for a replacement for paint. econokote is thinner and lighter and should work as paint and protection like tape. even if it wrinkles here and there, precision is only an estimate in the foam world haha But everything should work well. they claim that econokote flexes with foam and fiberglass so it doesn't split in a light crash. Even if it did split, a shot with a blowdryer will seal it back up
