Cob webs

Trying to paint the body of an rc truck with Spaz Stix Candy Apple Red paint and it is coming out and producing web like material.

Any ideas??

Hi buddy. Can you be kind enough and introduce yourself here:
https://www.airbrushforum.org/introductions/
Nothing to worry about, if you don't know what to write in your introduction, check few of them from other members, so I am sure you will know what to do. We all wrote our introduction, few of us needed a little push, like me for example, and you. :)

Not familiar with the paint brand but I agree with Erwin, a paint & thinner/reducer seems the likely culprit.

Any chance the paint has been subjected to temperature extremes ? (Frozen or hot for an extended amount of time)
 
I didn't put any thinner in the paint because this paint is advertised as not needing to be thinned. The following is what the company responded to me.

The cobwebbing is generally the result of spraying the paint too dry. So either your airbrush settings are not right, the temperature is high, or you've added a thinner. Our paints are already thinned, and ready to spray, so there's no need to add anything. Try turning your air pressure down and opening up the paint flow on your airbrush. Do your best to even out the coats in order to reduce the "dark" spots before applying your backer color.

you may need to stand a little closer, the paint may be drying before it hits the surface.

here come all the questions:)
Knowing what equipment you are using will be most helpful here.
Make /model/ needle size of your spraying equipment
Model of air compressor
Is it dry and hot where you live? (No location in your profile setting)

But i’ll keep going:
sprayguns need the correct air and paint adjustments to work efficiently.
airbrushes need the right air pressure.

Are you setting the regulator on your compressor with the trigger depressed on your brush/gun- if not your pressure will be to low.
 
I live in South Florida and it is always hot and humid. I use my regular air compressor and i set my pressure to 25 while pulling the trigger. I also was mixed up about the effects of the needle size. I had the .5mm in thinking it would give me the most paint. So I'm going to try again and I will lower my pressure to just below 20psi and switch to the .2mm needle and see how it will work.

Going to a smaller needle should be last on the list. 25psi seems to be a good starting point, try the brush a bit closer first.
Don’t have a fan blowing (or natural breeze)
strain the paint, (stockings over the bottle should suffice)
For future reference, always test spray in an identical surface before attacking a project.

The 0.5 should give you the highest flow rate. It does look like the type of thing that happens when you use the wrong thinner/reducer but you say you have used it straight so I would try thinning the paint a fraction with the correct reducer for the paint brand. Try a practice piece to experiment with the paint first.

Si is right, I’d pick the .5 needle
Grab a practice surface
Set the psi at 30 (I’m now thinking it’s not atomising properly)
Have the brush no further than 2 or 3 inches away and test spray LIGHT coats. Slow steady passes.
 
Ok so round two was going awesome until this last coat of Candy Apple Red was going on. Any ideas or suggestions??
Besides find a new hobby!!!

Practice makes perfect John, candies are probably the hardest to master along with clear coat. You will get it pretty quick, you got past the 1st coat, I don't know how many coats you did before it went wrong. We have ALL been there.
