I picked up the TRN-1 for its ability to shoot small amounts of alclad metal shades with very low air pressure. I really liked the feel of the gun and thought I might like the option to throw the amount of paint that the TRN-2 was apparently capable of doing.
I was able to buy all the necessary components from the mapleairbrushsupplies website to convert my .35mm TRN-1 to a .5mm .
This fluid needle being one of the four parts needed.
Once again the customer service that I received and the speed of delivery were outstanding
