And just a year later. . . @gblair, @fiveten and @johnb, I did wetsand and gave it another few layers of clear. The same problem with a new brand of acrylic clear (AK) appeared, bur after a few moments I were able to add a few layers wet-in-wet, and it all ended in joy!
Wet, Clear and wheels
Wetsanded the plane.
I wetsanded the plane
and after a day to dry it had a few layers of clear gloss.
Today I added the wheels
beware the wheels are handed, and I do not know if it is by design, but one wheel would not fit, so I changed them, and they fit perfectly.
now the wheels have to set, then it is time for decals!
