I have tried and used Monokote years ago and then switched to Ultracote. The reason for the switch to Ultracote at the time was because Ultracote will stick to lite ply and Monocote never would, unless you pre-treat the lite ply with something like Balsarite. Balsarite smells about as bad as butrate dope smells, so giving up using Monokote was a "no-brainer" to me. Aerokote? Yes I have a Sig Senior Kadet ARF that is covered in Aerokote and the only part I hate about the plane. If you touch it too hard or look at it sideways, the transparent will tear. Both the transparent and solid colors on the plane constantly need to be re-shrunk and require a lot of maintenance. I like Sig planes a lot but I only buy their kits because the ARFs are covered in this mess they call Aerokote.
