Moin Moin, I bought a used one that has a scratch on the rear fender and already has a bit of rust. The seller gave me two paint pens (originally from the manufacturer, base and clear). I wrote to 5 painters and showed 5 workshops the car, the answers were either to expensive or so they have to go somewhere else. As only good offer there was a paint for 150€ net, unfortunately there is no workshop anymore Since the car is already 20 years old I don’t want to spend more money there and have now bought me rust converter and primer for 10€, so much so good, I think the rusts I get covered out, But now my real question: Since the primer, base varnish and clear varnish is so thick liquid, can you squeeze the horizontals with neat varnish and plastic card instead of additional spatula mass? And then I have read a few times what you can roll instead of spraying, works well? gt. The car is 20 years and has 150.000km which should last 5 years but if looks better than now would be good. So my idea to remove the rust, a little more primer up, on the old sanded varnish neatly up the new base varnish and balance out, then roll over and at the end clear varnish (maybe I still buy this as spray) up, polish and finish? So the new paint keeps on the old sanded and you can paint the paint with a foam roller ? I’ve done this a few times, but I’ve never done this big before. Thanks in advance
