Just got home from where we keep our truck, having spent the evening putting acid etch primer on some of our suspension parts (axles, shackles etc), and bonnet.
Whilst spraying, I noticed that the gun is kinda going '... puh, puh, puh ...' as though there isn't enough paint getting through. Even though the gun is over half full.
There is plenty of air, and for the most part we're holding the gun upright as per normal, so I can't see a reason that it would be having trouble getting the paint through. Its the same gun and air pressure that we used last time, and I don't remember having the same trouble then.
Have we just mixed up the paint too thick? or done something else wrong?
For the record, my girlfriend (littletruck) and I are novices at this. Only had our truck just under a year, and the sum of our experience at spraying, is that we sprayed the chassis a few months back.
