Very underutilized tool in my arsenal maybe because I don't always fire up the air compressor. Your post got me thinking to break it out on the interior detail I'm planning tomorrow. I agree with 1:10 seems fine (APC & Folex).
I used it for the first time today on an F150 I'm working on this weekend. Worked great. I used APC 10:1 and no problems. This truck interior wasn't to bad but the places that had dirt in the grain if the armrests and sill plates cleaned them right up. I can't wait to get a really dirty car to try it on.
can anyone confirm that when using the tornador guns that you aren't just pushing dirt deeper into the fabric? i've seen some videos and it seems like it does that
