The short answer is "No". A bristle is not going to prevent anything from entering a garage that an intact existing rubber seal won't. These products do look great but in terms of effectiveness, they are (pretty expensive) gimmicks. Intact rubber bottom seals prevent ingress of both water and dust etc. and in this case, bristle seals are superfluous. We don't recommended bristle seals for the bottom of a garage door - a good rubber bulb seal is far more effective and appropriate.
Don't attach the rubber seals at the bottom of your garage door with an adhesive. Rather purchase a suitable carrier and affix it to the door. Then when the rubber wears out, you can simply slide in a new length.
