Re: air brush recomendations
I have used the Badger 350 and was quite pleased. I found a local deal on a Paasche Model H that worked just superbly as well.
I do find a dual action brush (mine is a Badger 155) to be a smidge better for the finer areas, such as in corners or slots, as it allows me to better control product flow coming into and out of the delicate areas.
Be advised though, the dual action trigger mechanism does take more practice to get proficient with.
If you think a dual action brush might be something you'd like to try out, Harbor Freight does sell a copy of the 155. Try a dual action without a huge investment, and the brush did seem to work.
