I just moved to NC from NY not to long ago and lost my my air compressor and shop Vac in the move. Its a long story but anyway I am wondering if this unit is worth the $? And does is work well? I used to spray interior cleaner in the crevices/moldings in the dash and blow it out with my air compressor. This may sound strange but it served me well in the past. Anyway, I was wondering if this product can be used in the same way. If so it may save some space and $.... I could potentially just buy 1 unit instead of two. Does anyone use this product in their shop? Your opinion would be greatly appreciated
