Strips work well, but yes, gluing is a bit tricky, you can get too much wicking and capillary-actioning all over, or too little and they pop off. I KNOW this sounds crazy (especially from someone who likes solid and overkill), but I used ragged strips of masking tape, then smeared green putty on, then sanded until almost gone, just slightly bumpy and irregular and barely there. The putty bites quite nice, and once primed and painted, doesn't flake off. easy to do and easy to fix/change.
Otherwise, if you're settled with strips, I would use a styrene solvent like Humbrol or whatever, because it can be pit on with a toothpick and wil bond well to the hull. (The poly liquid tends to evaporate very quickly and be useless on thin and small stuff.
