Just finished painting the hood,grill,tank on my IH Super M w/IH 2150 and hardner,no runs but did not get the finish that I was hopeing for. Looks like over spray and not a good smooth finish. Air temp was approx.55 and air pressure @ 50 lbs.

My question: Where do I go from here to get the finish close to what I want. I realize it is hard to fix a problem over the net ,but I have gotten some very good help from here.

Thanks
 
air temp was too cold. also, your last coat was probably not a "wet" enough coat. when shoot alkyd or the early synthetic enamels, ie "dulux", i shoot 3 coats. first coat is a tack coat, just enough to get color on, but it will be kind of transparent. let it flash, then apply a second medium coat to get good uniform coverage. let it flash, the apply the 3rd coat, a full wet coat. then walk away. an old time trick was to heat the paint in a water bath to about 120 degrees F. and then shoot it. made the paint flow a lot better. pan of water on a hot plate with a thermometer.
 

I just have to comment that just a very slight difference in how fast you move the spray across the surface makes the difference between runs and orange peel.
 
A dull finish is usually because you are using too fast of a reducer or moving too fast and not getting enough paint on.

The paint has to be just on the verge of running to get a good finish. Putting on thin coats to get it sticky than putting on thick finish coat is a good method.

Check the temperature range of your reducer. There are about a half dozen for different temperature ranges. I usually move down one number from what is reccomended so it will dry slower.
 
First of all 50 lb is way too much for any paint. Most of it will deflect away into the air. 25 lb is plenty if paint is thinned properly. Next thing is, it doesn't matter how many instructions one gets here or out of "the book". If that's all there was to it then everybody who can read can paint , first time! Practice and feel and learn! Comes quickly to some and some will never grasp it. You may very well have everything right (accept air pressure) but until you get a run , you will never get it to shine and lay out flat. Anyone who thinks a run is complete failure will NEVER get a good paint job. You have to go too far to know how far. Happy painting.
 
I'm just guessing but it sounds like you did not read the application instructions.Two obvious mistakes . But thats how you learn.
 
To B-maniac: Since reading your suggestion I thinned down the paint and turned down pressure to 25 lb. and shot some small things today and it woked good . Temp was 60. Thanks a bunch guys,I learned something that I wont forget.
