Stynylrez issues?


Recommended Posts

Hi guys,

 

So, I have the black, white and grey Stynylrez primers. The white and grey have always sprayed pretty well for me, but for whatever reason, the black is just a complete nightmare... I've now tried 2 different bottles and had the same issues since the moment I opened them (so really shouldn't be due to the freezing issue I've heard about). For a while it will spray perfectly, then stop intermittently before just giving up entirely. Weirdly enough, when I then inspect the inners of the airbrush the nozzle isn't blocked and I can't find any clumps or dried bits anywhere else. I haven't a clue why it stops spraying, and why it only affects the black.

 

Has anyone else had problems with the black? Is there any particular thinner I should be using? I think this is so frustrating because I love the finish of Stynylez and I don't think there's much better out there.

That’s strange mate. 
I’ve used most colours, mainly black though. 
Always neat and through a 0.3mm air brush. 
Yes a bit of tip dry during long sessions when its warm in the shed but nothing like completely stopping 🤷🏼‍♂️

It is weird! Do you use it straight from the bottle or thin it down?

I'm considering passing it through some kind of strainer to see if there are clumps in there that I'm just not seeing.

I have also used all three colors you mention and the only I had issues with was the white one, similar to what you are describing with the black. I don't think it blocked up entirely, but getting it out of the airbrush became much more difficult. What ended up working for me was simply increasing the PSI significantly for white. 

 

So I suggest either trying with a much higher psi (30+) first, but straining the black like you mention may reveal that you did receive some dud bottles. I've never tried this but you could also perhaps try thinning it a little with water? I also assume you're shaking the heck out of these before using them.

Try warming the bottle in hotish water, add a couple of mixing balls, shake really well, works a treat.  I spray through a 0.4 at 30psi, stop start etc, the needle does accumulate dried paint but a quick wipe and it's gone, it doesn't have any effect on the surface finish.
