Hi, I’ve been looking for a long time in the net but I haven’t found an exact answer. My question is probably not new. I’m about to bring my Ford Transit back to the front. I’m doing this for the first time and I’m confused about the different statements. My plan currently looks like this: 1. rust spots blank sanding with sandpaper 2. Place with silicone removal clean up 3. Place glue off 4. And here comes the cracking point. I don’t have a spray gun or compressor. I’ve made good experience with “Rostegal” with the frame of my trailer so I would like to use it here as well. This is available in the spray can. Can I take this or should I rather buy a bucket and apply it with a brush? Since the car is not a beauty I don’t have to renew before the original paint. For the renewal of the underfloor protection I already ordered Permafilm and Fluid Film Liquid A, should I just use it for the rust spots too? Or should I use something completely different?
