Terry, there are several brands of good quality spray gun cleaners that are made specifically for this purpose. Don't try chemicals made for cleaning carburetors or other generic solvents. We use a 3M spray gun specific product. They work very well at dissolving 2k primers & paints, so from my experiences the gun is savable.

The issue that makes guns repairable or not, is the soft parts (seals, o-rings, plastic cuts, etc.) availability. Many guns today are made to be 'throw-away' guns simply because the value of the labor to do thorough cleanings exceeds the value of a gun. Many spray guns are just like computers where the prices for new units is way less than what they were several years ago. Our spray gun of choice right now in the shop is a Sata 5500 which is under $1k new. Five+ years ago this was a $2,500 gun. It is on the edge as far as a throw-away gun. The DeVilbiss FinishLine gun is one of the guns we use for spraying primer, -and would be considered a very good hobbyist finish coat gun. The last I knew, these were in the $250 range new and are considered a throw-away gun meaning the clean-up time exceeds the value of the gun by the time the hours spent cleaning and costs of replacement parts are factored in. A Harbor Freight spray gun is honestly not worth the cost of the cleaner needed to clean it, so the answer to your question is yes you can save the gun but is it a value to do so.
