Hi guys, I’m turning to you today because I have a problem with a painting. It’s not about a body, but about a metal channel lid for a wastewater inspection shaft on my driveway. I wanted to repaint these lids with a metal protective varnish from the Hornbach and I used the _three_ old lacquer layers as well as possible, except for bare metal. After that I came up with the great idea of using rust converters (or that I used) to use an A rust converters dry/harden etc. and then the Hornbach varnish on it. Then looked good for several weeks, until I watered the front garden and the well water also fell down on the lid. At some point, rust was formed again superficially, but one could “wipe” it away and while the lid was wet, the varnish dissolved and became more liquid again. The varnish could be simply scraped, similar to the pick-up. afür ist I guess the strongly iron-containing well water, it generates again superficial rust and lets the rust converter work again and breaks my varnish?! Is this at all possible or am I on the wrong track? Shouldn’t the rust converter be “ready” after drying and not react any more? In looking into it, I think it was unnecessary to apply the rust converter, I should have painted right after finishing and everything would be good (I hope).
