Yes. Don't use brushes. Learn to spray-paint. If you must apply paint
using a bristled implement try paint pads or rollers.

I have been using foam brushes for stains and varnishes for the exact same
problems the OP had with brushes. I get them from the local pound shop in
packs of 20 in 3 different sizes so I have never bothered cleaning one.

The results are on a par with a gloss roller but much easier to use.
