I had my side wall and the wheelhouse welded, because my VW had the chamois at the typical weak point. I sanded the bare sheet metal with a 400 paper, then cleaned several times with silicone remover. I applied two thin layers of primer to it.This primer (click). Meanwhile, the primer is dried and you should apply the base varnish. I “measure” my paint and let it mix. If it doesn’t fit completely, no matter, How do I proceed now? The primer must be easily sanded (400s?), again with silicone remover embarrassingly clean and then 2-3 thin layers of base paint. Right understood?And with which clear varnish should I then complete the lacquer structure? I have something from Presto and still something from VW, which comes from a paint spray set.When does the clear varnish come on it? On the slightly wet base paint or only when it is dried? What I have, I still have f otographed, perhaps this elicits some missing information. Image of the base lacquer can, image of the “clear varnish”, image of the back of the presto clear varnish.
