An alternative to the fine spatula is wanted! I always have a little shiver over my back if I should touch expensive spatula mass for a 1 euro large rust stain. And, if necessary a second time, because spatula mass is lost just when grinding where it is bitterly needed. Specifically: I put in a photo, with the request: How can I heal the defective paint spots? What have I done so far! – Rust cleanly sanded off – Rust transducer 8 hours effect – Roststelle Cleaned with silicone remover – with filler at 21°C generously 3 times over rust surfaces – filler 8 hours dry out afterwards with 400 paper sanded problem: the filler does not fill the rust spot alone, because the adjacent healthy paint also gets filler. And the base paint does not compensate for paint unevenness. At hidden places my procedure may be OK, but what if it concerns the bonnet? There everything should be 100%-y! What did I do wrong? Thank you in advance for one and another suggestion. Greetings Kratz5842
