The best I have ever tried. Get it with closed eyes, it does exactly what it says. It has a slightly off-white color, not white. It requires attention and disciplined process but not difficult. You can easily avoid it from drying out as long as you paint at reasonable temperatures of 15-25 degrees. I have used it on many glossy materials and it is perfect. It sticks and does not come off at all. If you have, for example, galvanized iron fences outside, use it and they will never rust or peel off!!! Of course, after the VITEX WASH PRIMER, you will paint with a good plain color, for example, VITEX HEAVY METAL SILICON in the shade you want. Finally, in 90% of cases, paint with a very small roller or a large one, not with a brush.
