Hey Mark, thanks for your comments.

Yes, I made some errors: I did not sand between dye coats. During lacquer spraying I had a lot of issues, some dye went out and it was a mess (the dye which didn't soaked as you said). I used a spray gun for the first time and in total I made 12 coats of lacquer. The firs ones mixed with 25% water, and the last ones 5-10% ow water.

After 4 weeks drying, I sanded with 1000 and water, but I couldn't flatten the surface completely. Later on I will do a refinish as you said: sand the clear, add more lacquer and polish again.
