When you're spray painting, do not be shy. You can bet you're going to get some runs and if you do not wet the panel properly then its going to prove a dry look with lots of pitting pattern. If you happen to run over a clear coat, you can usually fix it after it cures. You will be able to run out of sand between two panels. Do not fall into the trap of cover-up. Meaning load on more material to try to cover up the mistake. It just does not work.
If you follow the instructions, at least your application will not be any problems as a result of flash is not enough time. What happens in this case as the application is curing the solvent in the material evaporates. If you add another coat before it fully took place then the material is going to flow. Do yourself a favor and always add a little extra time to cure. You can save yourself a lot of work and headaches that way. If the vehicle is not exposed, even drying time as it happens in a cross flow spray booths then tends to run cooler side.
Finally, you will get a perfect program, and then fly comes along and lands in your material. Do not panic. Use tweezers to carefully remove it. Hopefully it will be only a slight imperfection, which will then be able to sand the nails. Worst comes worst you'll end up respraying panel.
some common questions when it comes to spray painting techniques are as follows.
is a broad sample of the best techniques?
If you use a clear material, you may use a yak, but pay attention to what you're doing. You could end up with some really obvious bad patterns. perfect spray pattern must be perfectly even from top to bottom. The second thing you need to take into account and will have to contend with the over spray that occurs when a gun is wide open.
I have a HVLP spray gun can I use any technique you want?
You can not use regular techniques with this gun because it was given to 10 psi cap 50PS unlike in conventional weapons. This means that the distance will not be as great a HVLP gun, which means that you need to be closer to the surface color. For weapons convention, the standard distance with HVLP 8inches while it should be between two to four inches.
Will you be able to get more speed with HVLP?
Standard weapons transfer efficiency is about 25-30% with HVLP while it is around 65%. So needless to say, gun excels in this department. You have to remember that although the closer you are to spray the target area faster stroke. As you extend your distance, you can reduce your stroke. With HVLP, your goal distance is 2-4 cm.
