I recently bought a Paasche airbrush, the double action internal mix one. I
believe it's the VL. Anyway, me and my brother have only used it 1 or 2
times each and each time, except the very first time it was used, something
strange keeps happening. We each used it to airbrush lexan/clear plastic
bodies for our rc cars. After a minute or two of airbrushing our hands/the
airbrush and whatever we are painting gets covered in colored spyderwebs,
whatever color we are painting. This would be much more annoying but you
paint the inside of these bodies so it can look crappy without the outside
looking bad. Can someone tell me why webs of paint are forming EVERYWHERE
and what can I do to get rid of it? The paint we've used is specially
designed for rc cars. Also, does it matter if the very tip of the 'needle'
is bent slightly at the end. It's very fragile and seems to bend easily.
Also, my compressor is 1/10hp, if I remember correctly and if that matters.
Thanks

Mike is it the R/C Car Racing Finish Paint? I used that once to paint a
helmet. I got a jar setting infront of me now. I think its a laq base paint.
Thin it some with slow thinner, at least 50% see how it sprays. Light coats
so it doesn't run on you. Clear it when you're done. A bent needle doesn't
help, you just won't get a good pattern when sprayin. What psi are you
sprayin at? 35 is a good psi to start at then go up or down depending on how
its sprayin.

Chris,
The paint is Pactra Racing Finish, sounds like that's what you are talking
about. I'm already done my car and it didn't turn out too bad, but in a few
spots you can see really dark spots and lines of blue. That would be where
all the blobs and 'webs' landed. I didn't thin it out at all and didn't even
think to. Do you think that would be the problem?
My compressor doesn't have a way to set psi, there is just a screw at the
end of the pump where it connects to the hose, and when you tighten that,
all air goes through the hose. If it is loosened all air exits through a
hole in the side. Know what I mean? So basically all I can do is put it at
full blast or none at all. Is there some sort of gauge I can buy to put
between the hose and the compressor that would allow me to set it from
0-whatever psi? That would be VERY useful. It's a pain to keep loosening
that screw everytime I stop brushing, and if I don't pressure starts
building up and my compressor starts bouncing all around, which I know isn't
good.
Thanks for the help Chris

Pactra that's it! Not sure what comp you have, is that one of those little
jobs that run all the time and have no hold tank or shut off valve or
pressure relieve on it . I don't know if you can put a regulator on those
types or not. I have a Sears 1 1/2 hp with a 12 gal tank, reg, with an in
line moisture trap. Cost under $200. That paint like the candy laqs the more
you spray the darker it gets. That's why you got the dark blobs. I've
thinned that stuff 150% at times to get it to do what I want. I just sprayed
at a lower psi.news:8km4nc$l2g$1...@bob.news.rcn.net...

Chris,
I painted an R/C car body on the inside years ago with Tamiya
Acrylic paint which could be what this person used. Acrylic
paints are perfect for plastic car bodies like this because they
will flex and not chip.
