Any advice on DIY exterior house painting?

8. It's generally easier to paint your trim first and cut the wall paint up to the trim

That way you can go ahead and let the trim paint come onto the wall a bit and cover it up later with the wall paint on the flat rather than having to cut over an edge to an inside corner like on the side of your windows where they meet the siding.

If the trim is good and dry and something like a semi gloss the flatter wall paint will wipe off it while still wet if you make a mistake and cut too far onto it. The other way around doesn't wipe so well, flat paint absorbs another color enough where it's hard to wipe off.

Keep a wet rag around and only dip the end of your brush into the paint, once paint is running down the brush handle onto your hand it's time to go clean the brush, all you're going to do is get paint all over everything at that juncture.

A 1" deep or so dip and a *gentle* slap on either side of the work pot to clear the drips off and you're ready to put paint on with the brush. Larger areas the paint can be rolled on and then worked into the pores of the siding with a brush if you really want a superior job. Don't try to roll the roller too dry, keep it fairly well loaded up with paint and dip it fairly often, once you roll the fibers on the nap flat rolling too dry the roller won't pick up and hold paint as well.

If you are changing colors be aware that when paint goes on the wall it looks about two shades more vivid in color than the chip you look at in the store.
