Stynylrez Primers

[John]

I've read a lot about these primers and thinning is a bit of a no no, thinning any primer makes it a paint. a larger needle/nozzle is the answer.


From what I've read thinning them will reduce their self levelling propitites, and will also make them not adhere to the kit as they should.


As I said that's what I've read, I've not tried them yet.

Thanks for the replies.


Graham - I added my IPA to the thinners bottle itself. Allowing for what I've used and how much IPA I've added, I'm estimating I'm up to about 20%. It doesn't give me a % on my jar of IPA. I seem to remember ordering 99% but that must have been about 5 years ago. Maybe I should think about replacing it?


Ralph - I've also read it's very good, which is why I'm persevering. I spray at around 30 psi and I'm wondering if a higher pressure would help. I don't want to go too high though 'cos I only have a small portable type spray booth which I don't think would catch all the spray from high pressures.


John - I swapped the needle on the H&S brush I got from you and I'm using the 0.4mm - the largest I have. I really don't want to have to be swapping and changing needle sizes every time I swap between thinner and paint so I'll have to keep trying with the 0.4mm.


I agree that primers should not be thinned, but I just can't get it to flow through my brush any other way. I've been using the Halfords spray primers which always work really well for me, but I want to find a primer I can use in my A/B as I have to use the Halfords one outside. I've tried the Vallejo ones and I'm not really impressed - I just wish I could get this one sorted!

Primers rearing their ugly head again, I've only used Vallejo since I started middling last year and I haven't had any problems. I'd like to try stynylrez purely for its fast drying times.


I spray at 20psi with the flow wide open, ball bearings in the primer bottle and shaken really hard, never thin. I use a h&s airbrush exclusively for priming now and strip and clean it after every prime. I even have plans for a Iwata (probably something like a HP-TH) airbrush at a later date, this type of AB will give a broader, easier flowing, even coat. If you hate priming and just find it a headache this may be the perfect solution for you.

I tend to use the 0.4 needle for most of my spraying, using the 0.2 only for when I am doing very fine detail like mottle camo, Badger themselves recommend a larger needle. I also would suggest that using ipa is itself a problem. Try first of all spraying unthinned with the 0.4 at 25-25 psi and, if you need to thin use Vallejo or AKI or thinners rather than ipa or anything else. These seem to be a better 'chemical match' than ipa or Tamiya that can turn some types of paint into a sludge.
