Basically, the chaos black spray sold by gw is an acrylic based spray which I think is overpriced- is there any difference between using that or using a cellulose based spray that Costs a couple of pounds in the hardware store

What are the differences? And will it affect my models in the long run


Thanks

Don,t know but I use the army painter matt black which is very good even if abit more than the cheapest.

I use Rust-Oleum ultra flat black from their camouflage collection. Its inexpensive and covers beautifully.

I've used cheap car sprays and other cheap sprays in the past. They're fine but you have to be so careful with your passes, it's very easy to flatten all the detail of a model. The GW spray is expensive, yes but it is good.

Lucas.

Or just grab a reasonable spray gun and some Vallejo black surface primer. The primer is about the same cost as GW spray, but as it is just the liquid with no propellant (Hence the nead for a spraygun, but I'd recommend something other than the GW one) it lasts at least 4 times as long.

Before switching largely to Vallejo PU primer, I had always used cheap aerosol enamels on plastics. Never had a problem with filled details - the Walmart house brand (ColorPlace) flat black goes on exceptionally thin and smooth, actually. If working on metals, where an actual primer is necessary for any degree of durability, I used Krylon Indoor/Outdoor Primer. Thicker than the flat enamels, but still pretty easy to lay down thin coats. Considering the range, quality, and price of 'hardware store' options, I'd never pay for GW undercoats or varnishes.

Before using spray paints, make sure that it is indeed a spray primer and not your regular old spray paint. A spray primer will provide tooth for your paints to stick to.

And yes, they work just fine. I prime with cheap spray primers almost exclusively and they never fail me so far.
