Painted my 1st full vehicle, I am pretty happy so far......

I cut thru the clear and color to the sealer in a few spots, maybe 10 in total including some bad masking spots.

Anyway, I tried hitting a couple of these spots with my regular HVLP gravity gun, but is is too big and even with the pressure way down, and fan small, the paint wont atomize right.......it is ok in the center but too dry on the edges.........

all I need is 1/4-1/2" by 1-2" coverage......

should I buy a cheap airbrush?

what is the best way to blow color on these small breakthroughs?

what kind of paint system did you use you might get away with a blend but sounds like you might need a diff gun

paint is all Dupont Premier line, all urethane, all applied by the book......

What do you pros do when the boy in the prep shop cuts thru your nice job other than ride him?

My thought is one of those little badger airbrushes might be just the ticket......i'd probably have to use more reducer.......

i would tell the kid were to go most hvlps have a 1.3-1.6fluid tip size i would either get a smaller gun with a smaller tip if youre hacken or just blend it out with a normal HVLP gun and clear it unless u got a flame paint job or something like it.

you can try the two gun method basically wet sand the entire area around the repair spot with 1500 then put base coat in one gun and reducer in the other spray the color coat in a big arc, the object is to feather into the repair spot, next wet the overspray with the reducer in the other gun then put clear in the gun and repeat the method used with base coat but extend beyond the base coat you will have over spray on the existing clear this is ok becouse now you grab the gun with the reducer and wet the entire area thus liquifying and melting the overspray clear into the orig clear let dry then wet sand repair are with 1500 and wheel out the whole panel.

it is cool i learned it at auto body repair school and actually used it a couple of times, it is not as bad as you might think, but for the small are you are talking about you could almost fill it in with touch up paint or have your paint shop put some productin a spray can, then feather out with 1500 rub and done.

Sorry but that repair plan of spraying part of panel WONT LAST.
UV rays from the sun will ruin that blend edge, in time you WILL see excatly where you blended that clear.

No paint manufactor that am aware of has a warrenty for this procedure.
meaning you do this they WONT warrenty the paint, its now void!!

Plus you need a different product to do this other then reducer. There are clear blending agents that are made for this purpose. But keep in mind even these products fail when exposed to UV rays. Their purpose is for cutting or blending in jams of cars where no UV light will be seen.

Repaint the panel, color blend the cut throu spots then reclear then entire panel and be done with it.

If you do get another gun, an airbrush is not the answer. They are great for small parts and details, but they won't let you blend on a panel. Get a small touch up gun (Jamb gun). Even a cheap copy of an expensive gun will do great for this kind of work... :cool:

BTW-sevt_chevelle is correct. You blend a panel by over reducing and it will come bavk on you sooner or later...

please use a good gun for blending. i would rather spray a whole car with a cheap gun than try to blend a panel with something that wont atomize correctly.
