Damn

Well after screwing around for 2 years painting my car I put a big dent in it. Since I had taken out the radiator to remove the hood I decided to change out the hoses. I had a lot of trouble getting the lower radiator hose on the water pump. I was leaning over the front of the car (thought I was being careful) and put a large dent in the nose.

I have had nothing but problems painting the car. I painted it before without much trouble. I purchased a new fairly expensive HVLP spray and have had a lot of problems with it. Main problem was dry spray which included a lot of overspray. Just didn't seem to get the coverage like my old conventional spray gun. I ended up respraying most of it several times. I used acrylic lacquer as I did before. I kind of wonder if the new guns are set up for the newer paints? It looked fine after I finished sanding and polishing it but now some flaws are showing up. I think the paint is already starting to fail so I'm very disappointed after all the work I put into it. The one thing about the dent is that it makes the other flaws somewhat disappear. I thought about repainting it but I'm tired screwing around with it so I'm just going to finish putting it together and drive it. At least I won't have to worry about getting the first dent.

So the poor thing survives being hauled in a trailer by Hoppy down into Reno only to be dinged by you? Oh the horror. Did you get a gut or something to be doing that while you were leaning over...Christ, I haven't even done that.

Color?

I feel your pain. A dry spray can be caused by the vent hole into the cup being plugged or blocked. Just and idea to check.

Is the new gun a top feed? I have a newer top feed gun and have sprayed lacquer many times w/o incident. I had a lot of trouble with a bottom feed gun though.

make sure you have around 30 psi at gun and around 10 psi at trigger for hvlp guns you probably know that, my experience with my gun which is a devilbis milleneum is that it sprays to my liking with 15 psi at trigger and it did away with a lot of the dry spray and also slowed down on my movement when spraying the paint, also like the other gentlemen said make darn sure the vent hole is not clogged!

Jamo, It wasn't my gut I think it was a knee. It occurred where I had welded up a hole in the aluminum. I probably annealed the metal. It was so soft I pushed it back up with my fingers. Still has a wavy dent. Frustrating after block sanding so much.

I was using a Devilbiss CVi with a DeKups system. The gun recommends 26 pounds at the inlet to the gun which is supposed to end up with 10 pounds at the tip. I finally dropped the inlet pressure to between 18 and 20 pounds and it seemed to get rid of the dry spay but then had some orange peal. I even changed pressure gauge to make sure it wasn't a problem with the gauge. It still had a lot of over spray. It also didn't get coverage around edges as well as other guns I have used. I had better luck and less over spray with conventional guns including a cheap one that came with a craftsman compressor.
