I thin the melamine50:50 with cellulose thinners to allow it more drying time and the lines “ flow out “, like with gloss paint . I also use a VERY FINE flat brush to apply it keeping the brush moving. If needed dip the brush in cellulose thinners and apply as SMALL touch to any lines whilst the finish is tacky. This sometimes works but only sometimes.
I think Eamonns method statements above are good though , especially for hybrid blanks .
