Hello all! got a question regarding body filler dust, dirt, grindings etc. have a 65 fastback and had to do the usual stuff, floor pans, wheel houses, quarters yada yada. im nearing the finish line on the shell and am wondering or just plain overthinking this whole thing but how do you guys after extensive body repairs get all the dust and dirt out from all the cracks and wherever before shooting any type of paint? im thinking compressed air a shopvac and a wipedown. just wondering how the pros do it? thanx

 

I would vacuum then, air, then wipe down. Any remaining dust could get blown onto your new paint job while you lay it down, IIRC.
This is what I've seen on various shows, I have never done it.

 

i use two air chucks screwed together...then i wash the car usually then blow it off again. then wax and grease remove the surface...
