Question about Northern Tool Vaper 2.0mm Hvlp Spray Gun with Stand 19120

Vaper primer gun has intermittent air supply

I purchased vaper 4-piece triple gun kit. used it once and 1.4 primer gun spits. 1.7 finish gun works o.k..I returned kit for free replacement & new primer gun is good for 1 use only. I thoroughly cleaned primer gun but when I tried to use it I can see bubbles coming up thru paint cup, Indicating to me that air is escaping thru cup.Repeated cleaning does not help, so I try finish gun to check air supply & it works fine. Is there repair kit for something in trigger line concerning air supply?

Does it come with instructions? The material thickness is VERY IMPORTANT when choozing the proper nozzle.

What is the best way to lay down the clear coat over my finish coat on the fender I just painted but ruined when I shot the clear coat?

Refer to the paint manufacturer's data sheet to ensure the new gun has the right setup for clearcoat.

Could be the new gun was supplied setup for spraying a high solids primer or something that needs something like a 0.7 mm fluid tip. Clearcoat would need a 0.4 mm tip, an appropriate needle and a different air cap.

Data sheets are very valuable things. Don't forget to pick one up when you buy spray paint. A viscosity cup is another useful addition to the tool kit along with a graduated paint stirring stick.

Will vaper spray gun do latex paint

Yes is the short answer, but you will need to use a latex wet edge extender (X.I.M) makes one most paint store should carry it. You can also use a bit of water, no more than 10% or as detailed on the label.
Keep adding the extender or water until it stops shooting spatter an has a finer mist.

What causes fisheyes using an inexpensive HVLP system with Tremclad metal paint on aluminum?

Here is some information to solve the problem.

Fish Eyes: A surface depression or crater in the wet paint film. Fish eyes are caused by repulsion of the wet paint by a surface contaminant such as oil or silicone. The depression may or may not reveal the surface under the paint. Make sure the surface is clean.

Etching Primer
If you are going to be painting any aluminum, you are going to need an etching primer. This primer can also be used on steel. It is two-parts (not like epoxy, though) and tends to "bite aggressively" into the metal. It really stinks to have your paint stick well to your primer, but the primer releases from the metal. One of the major benefits is that you can paint over the primer in 1/2 hour, about the time it takes you to clean your gun and mix the paint.

Additives: You can get anti fisheye additives, hardeners, flatteners, catalysts, metallics, metal flake, pearls, and reducers to mention a few. Get an anti fisheye thats compatible with the paint you use.
Masks Use a good quality dual cartridge mask for all work. Don't skimp, get the charcoal cartridges, they stop most aromatic vapors.

New to spray painting and am spraying baked enamel paint

To fix this problem you need to turn up the pressure both at the wall(coming from the air compressor) and at the gun. I would suggest 10 more psi at the wall and 5 at the guns but you can play areound to find whats best for you.
