Just sprayed by bearcat with tamiya pure white rattle can, it seemed to come out ok, but after about 2 or 3 seconds it started to run off. I didnt put it on very thick, but it doesnt seem to want to stick to anything, primed or not. Its pulled away from any paint already on there and just dripped off. it seems to be really watery straight out of the can and has zero coverage. I dont really understand what im doing wrong, if anything?
Any help would be appreciated.
Thanks heaps in advance.

Some rattle cans need to be shaken a lot, especially the first few times you use them. I do not use Tamiya paint, so cannot speak for them specifically, but with new cans a minute of shaking is the absolute minimum. In fact, before using a new can, I lay it on its side for half an hour, roll it over on the other side, and with cans with flat top covers I let it sit upside down for awhile, then still shake it for the full minute.
Use of a good primer also alleviates this type of problem
^^^ Agreed with the above.
Some batches of rattle can paint are duds. Never had trouble with Tamiya’s Flat white…Gloss white is different in that a base coat of flat white will help.
Another trick is to heat the can under hot tap water. Somewhere I read heat it up in a pan of hot water on the stove… I do not recommend this as if you forget or it over heats the resulting explosion could be lethal.
I just get the tap water hot and run it over the bottom 1/2 of the can as to avoid the top where water can mess up the spray. When you feel the can warming shake, this will disperse the heat and cool the can. A few times is enough. Basically if a can can stand a hot day in the desert then hot water will not cause a rupture.
Spray something other than your model first, like a piece of wood or something with texture. If its satisfactory then its ready for your model. If globs or sputtering of paint happens you can change the nozzle, if that does not work avoid that can on your model.
When done spray upside down to clean the nozzle until just propellant sprays. Wipe the tip with a cloth.
*Its better to spray a few light coats vrs. 1 heavy one. Practice on something other that your model until comfortable with the properties of the spray can. Start before and in a smooth motion stop past the model. Its wasteful but the best technique. A distance of about 6" is best. For gloss you need to be braver and its more tricky, like said above practice first!
I am a ‘rattle can’ guy. Best thing is no set-up or clean-up time.
Also for the cost of 1 tiny hobby jar you can buy the can. Krylon for plastic is excellent and I recommend this brand for gloss yellow. Hobby spray cans do not work as well in yellow, a base coat of flat white really makes the yellow vibrant & is required. Caution as the Krylon is a bit ‘hot’ that is it may bite into un-primered plastic.
My experience with Tamiya Spray is limited to just 1 use last year. For the most part I use Acrylics and when it comes to spray, Model Master will suffice. I was using a Tamiya rattle can of red to paint the rear section of a 1/32 Mig 15bis. I noticed immediately that if I kept painting at the rate I was, I was going to have my paint running. For what I experienced then, it is very thin and requires several thin coats instead of one or two. Works very different to Model Master spray. I achieved what I wanted, but had to lay like 5 thin coats.
Thanks guys, I know about the thin paint stuff, thats not the problem, tamiya whites are the only ones ive had problems with. After letting the model dry, it looked like i had poured wood glue all over it. and it seems to have melted the undercoat and a couple spots where i had used marker to remind me where i needed to do some work (and thought i had completley sanded out) seeped through and left purple streaks. ill upload photos tommorow, its quite bizzare, ill try some of the tips, but i dont think thats the problem.
