i certainly wouldnt recomend the use of scuff pad or any abrasive material to clean a spray gun ,the idea of scuffing is to increase the adhesion of paint to any surface ,i have myself polished the internals of my guns and the needles which is a tunning technique ,scuffing would be a de tunning technique imo all that said flushing with solvent is all that is normaly required to get any gun perfectly clean
when it comes to polishing internals then i use polishing compounds often on a suitable pointed dowl which will conform to the shape of the internal part ,a cocktail stick or scewer doese nicely for the inside of a fluid tip ,i use a slow speed rechargable drill ,which i also use for polishing the needles ,they can be refined on 1500 paper then 2000 then trizact then compounded up to mirror finish
like polishing and porting an engine this will optimise fluid flow and also make future cleaning easier
with due care and atention airways can also be polished for increased laminar airflow
Wow! Ported and polished guns. :huh:
Actually I can see the benefit for cleaning and at the fluid tip. I tried grey Scotchbrite on an aluminium cup a while back. Scratched the crap out of it. Think I might just stick to soaking, round toothpicks, bottle brushe and soft cloths.
Wot a weird thread, you would think it was some old ancient secret tradition handed down since the birth of sprayguns, secret handshakes an all that.
I dont like the idea of abrading anything on a gun so i dont want a pm 😛
Yes, it is a bit strange. The only reason I’m not letting on in public is because that is the way Hub does it, so I’ll respect that.
And I wouldn’t want to go near a gun with a scuff pad anyway. For really stubborn stuff a microfibre cloth soaked in thinners is the harshest thing I’ve ever needed. I’ve never heard of anyone polishing a guns internals, but in theory it makes sense.
i mainly tune my aibrushes for increased laminar flow and hign detailing ability which requires instant reaction ,some of my airbrushes are as small as 0.1 tip size ,i also rematch aircaps to nozzles to optimise the venturi action ie vacume that pulls the paint through the tip
