Would it be better to rag it on? Or thin it? Ay suggestions


You can get beautiful results with this stuff but you have to brush it on perfectly. Any overlap and you have uneven results. If he really wants to do it, he could thin it some with mineral spirits and also keep a can of spirits to dip the brush to keep it open a bit longer when he needs to brush out the inconsistencies.

However, I would suggest the best solution at this point is to select his favorite color of interior gloss or semi-gloss latex.
