Badger 100LG Acrylic Problems

Are you able to spray windex or water through it?

you most likely have a clogged tip. 

a small wire ran through all the little holes on the tip may help.

or you could be lazy like me and buy a whole new tip.

How do you do this? Acrylics don't dry that fast!

Windex isn't going to help tip dry. If anything it will accelerate the tip dry. Windex is mostly water with Isopropyl Alcohol, which is why it drys streak free when used as window cleaner. The alcohol dries very fast.

Im not familiar with badger 100LG AB. I have an old badger AB that I have been using  for priming my model kit but I am not having problems.  I clean mine using lacquer thinner.  I dont know if your AB is made of composite materials, metal and hard plastic.  If your Ab is all metal you dont have problems using lacquer thinner for cleanning your AB when it is clogged with dry paint.  Another reason why your paint isnt coming out too well is maybe the pressure in your compressor is too low I suggest that you adjust the setting of the pressure of your compressor..  secondly maybe the mixture of your primer paint and thinner is not right.  I am suspecting that your primer paint is not properly thinned.

for best result when using acrylic paint that are water based thinned it with 95% isoprophyl alcohol and when you are using thinner base acrylic paint use Mr. Color thinner or Tamiya thinner to achieve best result.  My method for priming is I use the mixture of Mr. surfacer 1000 and lacquer thinner. 

Okay, one more time.  If paint is getting into the air valve and trigger area, you've either got a bad needle bearing or you are trying to clean your brush with the needle removed.  The only way paint gets back there is through the hole that the needle passes through.  The needle bearing seals that hole so that only the needle gets through and not the paint.  If you remove the needle and clean the brush, paint and/or thinner can leave the top cup and flow back into the brush.  At this point, you need to remove the air valve and soak the brush in lacquer thinner because it sounds as though paint has gunked up the innards.  If paint is in the air valve itself, you have to get a small allen wrench and unsrew it.  The air valve seal is probably toast but they are cheap. The rest can be soaked.  Make sure you dry everything out before reassembling and replacing the air valve seal.

Read your last post more thoroughly.  If you've tried to unsrcrew the tip, you may have damaged it or the needle tip.  Badger makes a three cornered reamer to remove the tip without damage.  A new head assembly cost about fifteen dollars.  To clean it the head assembly, you can remove the whole thing and soak it as a unit.  Also, a good set of cleaning brushes is worth the investment.  HTH
