Is it just my house or has anybody used this as your primer for figs and come back an hour or so later and find 48
fuzzballs on your painting table. Some 1st WW figs I had to pluck 3 times. I can watch tiny hairs (4 cats) floating the the light above then diving onto my figures. Its like trying to pluck a chicken while you baste it.

It could be the humidity level? I'm guessing if too dry, there's an electrostatic charge attracting the hair?
But also, I did have a bad experience with the white Tamiya Fine Surface Primer myself. I used it on HaT Sea Peoples (after washing them with soapy water, and allowing to dry). The paint did not adhere well, and formed lumps or globules as it pulled away from the plastic. At first, I thought it was the plastic because HaT has used a variety of different plastics from your traditional, to soft rubber, to hard brittle plastic type. But then I tried a regular white matt spray (made by Rustoleum) from Home Depot and it worked fine.
I also realized that I was able to spray about 2 or so sets of figures (lined up in a row), but got about 6 or so sets done with the Rustoleum can for the same price. Now my go to primer, is the Premier paint+primer (white matt) can, which I get from a store called Canadian Tire.
Btw, another fix to get primer paint to adhere well to certain plastics (like soft rubber), is to prime (before the paint primer) with floor varnish!

I use Krylon Fusion (well I did until I couldn't find it anymore, but still have enough left for awhile); anyway, the last batch I sprayed with Fusion stayed sticky. This has been over a year ago and the figures, which have been laid aside for awhile as my painting has gotten sidetracked for various reasons, are still a bit tacky.
These are the Prussian Landwehr which I helped crowdfund and the box got misplaced in the queue. I'm wondering if anyone else has had the problem with this particular set of figures? I don't know whether it's the plastic or just a bad can of paint as I've not had problems with either the brand of paint or the plastic before. At the same time, it might be humidity and the temp on the day I sprayed them - it was a cool damp day. Not a big deal, I do hope to get things together and finish the Landwehr - long overdue, I think and the queue is getting longer.

Waynew, I've had the same problem - stickiness of certain figures (not painted those Prussians though) after priming and even subsequent painting with acrylic or enamel paints. This is why I evaluated a whole bunch of different primer sprays from the Tamiya to the expensive Citadel Corax. I concluded the stickiness was related to the type of plastic used for particular sets (made by a certain manufacturer, and for any made of soft "rubber") - but I was able to find the cure which was to pre-prime the figures first with a coat of wood varnish(!) which was Rustoleum Zinsser Bulls Eye Shellac varnish (obtained from my local Home Depot). After application to each figure with a brush, then 48h later spray-prime and paint as normal - stickiness was gone! It's an extra step, but well worth the effort to eliminate that stickiness, and the primer paint then also adheres well to the coat of varnish on the figures. Though yet to prove, this varnish coat it might also help stop any paint chipping or flaking off. I only do this extra prep step for certain figure sets though.

Hello,
i got the same problem with the HAT-Prussian Landwehr-Figures.
My primer normaly works fine....ITALERI, ZVEZDA, HaT-Figures....no problem with this primer..
But as i sprayed the HAT-Landwehr with this primer the figures stay sticky. Acrylic paints do not adhere to it....so i tried to clean the primer from the figures.
I used brake-fluid, but this does not work. I tried it with other primer-Sprays, but they dont work better. Think this soft-rubber-plastic don't likes primer-chemicals...
Finaly i have painted all figures with thin emanel-color, let them 10 days dry and then started final painting with acryl colors. |

Interesting, as I've painted several HaT sets in this (or similar) plastic but have never encountered this problem before. I normally like the soft plastic BECAUSE it seems the paint adheres better to it. Thanks for the suggestions.

Still using it til the last can is gone. Going back to regular white primer from Home Depot/Lowes. Even the cheap 1.99 primer they had works better. The fine surface enamel may be designed more for plane, ship, and vehicles then the softer plastic of figures.
On another problem who else notices when a jar of enamel spoils? The point in time where the solvent will no longer mix with the pigment. There is a definite odor to them when this happens. I wonder if that can happen with primer where the solvent used no longer mixes well with the primer pigment which would leave it sticky permanently. I live in the desert scrub near the coastal range in Calif so humidity is not a problem til fall. I use a mix of enamels and acrylics so I don't have any bleeding of paint.

plasticpanzers, yes sprays/enamels going bad over time could be an issue for sure. But I usually have stickiness issues with plastic from a certain manufacturer in particular, tried over many sets at different times (using different cans). So one day I took only half a set of figures, and pre-coated those figures only with the wood varnish/sealer, then 48h later used the same primer spray can to spray all figures at the same time. Once dry, I tested the figures (by touch), and found only the ones with pre-coat of varnish were perfect - no stickiness whatsoever. Whereas the untreated/sealed figures were sticky, as expected. For me, this definitively ruled out the spray can used itself, and also humidity/environmental conditions in one go. Btw I still have those figures and till today (a year or so later), just primed (not finished) and sitting in a box on my shelf - the untreated ones are still sticky and the pre-treated ones are fine (dry).
And like you, I've had great results from the cheap paint sprays from Home Depot, and Canadian Tire in Canada - and now use only these rather than the expensive versions for modelers such as Citadel, Tamiya and Testors which give little bang for your buck.
