I have an oil painting created w/thin layers of paint. Only medium used was linseed oil. They have been drying for no more than a week. Some of the paint have a glossy effect, some colors are dull. I am giving this to somebody before I am able to put a varnish on it. Does anyone know any tricks to bringing a consistant glossy effect without having to wait the 1-6 month drying period? Or any varnishes that I'd be able to use while the paint is still somewhat wet? Any help appreciated!!
