If you need to to extremely long strokes at sooper close range, scrapin' don't cut it buddy. i have been using primo paint for a long time back when you could carry cans in your knap sack on a plane, back when Sparvar was the shit, and I can tell you this paint is definitely raising the bar.
I tried painting with Krylon recently and that was mad discouraging. I'd rather not paint if I had to use that ish. If cats are doing ABC pieces, just about anything will do, but there is definitely something to be said about people elevating the artform.
The bottom line about rusto is that it and krylon have limits, and no matter how dope you are with it, you'd be way doper using higher quality paint.
There is a reason that the European wirters are burning so hard, many of them have standards of excellence and strive to be the best.
I have painted in China using their shit brand paint and I can say as watery as it was I still preffered it to Krylon and rusto, simply because it cut better, and produced clearer lines. I painted with the best that was available at the time. Now that I am home, I do the same, and Brand K and Rusto no longer cut it.
