Help with Fluorescent Colours

[Dhami1]

Hi chaps.. i need a bit of help with flu colurs. here is what im using;

Iwata HP-CS airbrush - 0.35mm needle
Ripmax Silent compressor
Patrca Acrylic Paints

And here is my shell;



The problem im having with is the flu colour in the middle, its a mix of flu red and orange..(still not found the right colour.. a bit too pink)

everytime i spay the flu colour it doesnt seem to set right, and has a very coarse feeling on the shell. Its like the paint has set before it has even reached the shell, its causing the flu colour very suseptable to cracking.. what am i doing wrong? ive tried diluting the paint with a bit of acylic thinner..but no different

any help will be appreciated..

thanks

Hmm, its a tuffy this one. I use the pactra acrylics and they're fine.
I do use a .5 nozzle, so thats the only thing I can think of, as the flo' paints are a little thicker. It could be that its making the paint spray 'dry' so it effectively craeting like a dust rather than a spray?

Can't see any problem mixing them as long as they're the same make of paint. You've made sure that both colours are acrylic haven't you? I know it sound a silly question, but it has been known to happen.

Other than that, are you applying the paint in thin coats? and not in thick coats?

yes mate.. its like im spraying dust!!.. its a good way of describing it.

im using the same type of paint, pactra acrylic. The 0.35mm needle is fine with all the other colours except the fluorescent... so maybe i need the 0.5 needle to get it right. i thought the thinner would have had the same effect as this, but will give it a try i guess.

thank you
