The plastic of the kit is not that good too. I had a lot to do, until the paint was smooth and shiny. I used three different clear coat with 5 layers of it. At least the body is ok. Man, I'm not a fan of that piece of plastic.
Then I noticed, that the glas made canopy has to have partly bodycolor. The same like on the body: after 4 layery of paint, there is still no shine and smooty surface. What the hell of material Gunze took??
