I've used Vactan for years, it's always been straightforward. Yesterday, having spent several days sanding down a 6-10 inch strip of roof (many layers of blue antislip paint), plus the handrail above it, and the blue frame around the the boat sides, I applied Vactan. (There had been a LOT of rust, especially on the roof). The Vactan went on the same as it always does. A few hours later when I went back indoors, the Vactan was dry and everything looked normal. However...
This morning I came outside to find all my red and cream paintwork, and even the window frames stained with dirty blueish streaks. I've given it a scrub with a wet broom, but it doesn't come off. It's totally b*ggered. And I'm rather upset about it. This is about 25ft of cabin side. 😲
Any ideas why this might have happened? I've never had Vactan run like this before, and certainly not hours after drying. I would like to avoid this happening again coz there's plenty more rust to tackle.
Also, if anyone has any tried and tested methods of how to safely remove the blue streaks from my red paintwork and signwriting, that would be great. I've got a horrible feeling it's permanently fooked 😕
