Tip sizes vary from 0.8mm to 1.2mm and fans from 100mm to 180mm.
I use mine for painting small parts or narrow sections where the size and paint usage of a full size gun would just be a waste. Imagine painting a set of parking sensors that are only 25mm diameter with a gun that has a 300mm fan. A bit silly, apart from being wasteful, you'll agree. Wheels are another example where you want to be able to place the paint accurately on the spokes and not run the risk of excessive overlaps where runs could be the result. Painting tube is yet another example. Door jambs with a 1.2mm gun are much better and easier than with a big gun.
They're also used for SMART repairs, where only a small section (usually the size of an A4 sheet of paper) is actually painted. Again paint placement and blending control would be impossible with a big gun, but a smaller gun will do it easily.
They're also useful for things like misting metallic over black for a shadow chrome effect and for doing little spots that an airbrush could do, but would be stretched.
I have 4 dedicated touch up or mini guns:
- Star S2, 0.8mm - I love this little thing. Gets into tight spots and sprays almost like an airbrush but can open up to a fan around 100mm with a perfect tulip shape.
- ANI R150 (1.0 and 1.2mm) - Nice small guns with a very even spray pattern but a design fault in the seal on the fluid tip that is thinners sensitive and needs regular replacement. These are about to be replaced with the new Iwata AZ4.
- Devilbiss SLG mini (1.0mm HVLP) - The perfect gun to mist blending thinner with.
I also have a few midi guns that are bigger than those above, with tips from 1.3mm to 1.5mm and fans in the 150-200mm range, which I use for in between sized jobs. Those are all Star, S1000 and an old S710 that is the best primer gun I own, but too small for bigger jobs.
For the weekend warrior painting complete vehicles, I'd think that 3 or 4 guns would be enough.
A decent 1.8mm for primer. Devilbiss FLG5 would be a good choice, as would the Iwata AZ3 HTE.
A combined basecoat and clearcoat gun with a 1.3mm tip if you're meticulous about keeping it clean. Devilbiss often do deals on their ProLite with 2 aircaps and the T110 for clear with TE20 for base would be a good choice - like having 2 guns. Otherwise, and I prefer this option if the budget allows, separate basecoat and clearcoat guns. The Devilbiss FLG5 is also a good, cost effective choice although the 1.4mm tip could be a bit much for some.
A 1.2mm mini/midi gun for those smaller jobs or areas. The ANI R150 is very good but just not suited to daily use. The Devilbiss SRi ProLite is a fine gun but ridiculously priced. Iwata have a good range of mini/midi guns and, as I said above, I'm going with the AZ4 HTE-S in 1.2mm; simple design, well made with good performance and easy to clean.
my vehicle had some hail damage, I want to spray tail and one front bump about my Honda accord NH797M. my plan is buying guns for respraying, as my equipment. any idea recommend.
thank you very much for your point, it is very hopeful.
