Okay, so my dad's birthday is coming up and he is in deperate need of a new washing brush. Try as I may to get him to try something different, this is the only thing he will use to wash his Trailblazer. So now I'm thinking, instead of him going to the local truck shop and buying the synthetic wash brush that they have there, I should buy him a boars hair from autogeek. Anyone use these? I'm wondering about the longevity of one of these brushes. I don't want him to have to replace a $50 brush every 2 or 3 months. I figure one of those with a pair a gritguards would be a great gift. Any feedback on the brush, or another you would recommend?
