Were you spraying? or rolling. I have never had any issues with Timeless when spraying it. I know others have reported this. With the Wagner Control Spray Plus (it's basically the same unit as the base wagner, but has a separate compressor and hose) I make two passes, one vertical, one horizontal, then let this dry about 20 minutes. After that I will continue with horizontal passes till I get the coating where I want it. I let each coating dry 20min. I spray with the canvas hung at an angle, about 35 degrees. My only issue (which is a problem with all gloss coating) is getting a hot spot, where the glossy is a bit heavier than the rest of the coating and this of course will show on the final print. Hot spots are mainly due to human error, where you inadvertent let your hand get closer to the canvas briefly. It's a common issue with all glossy coating processes. Since Glamour II self levels and is slower to dry, the issue happened less often for me.
One other thing I have learned. With Timeless, on a matte canvas, you need to let the canvas outgas for at least 24 hours. If not the outgassing will definitely create bubbles. On a glossy canvas, you can go straight to coating with no wait.
Glamour II has a longer drying time and thus the bubbles don't form. It's a bit more forgiving, but I prefer the look of Timeless. It's an individual preference.
