I have some rust on the bottom of my door on the inside. I was planning on sanding it down, possibly do some bondo and then paint it. I was told before to sand down rust and then use a rust inhibitor then primer/paint. Now when I was at the local auto store I saw a product called Rust Block and its a rust inhibitor. I also saw in same aisle Duplicolor rust fix. The Rust Block states to sand then spray on the surface and it will last up to 6 months. The rust fix says to sand but also sanding is not needed but to spray the rust and it will turn the rust into a black color which stops/kills rust.
My question is which product/ processs should I do?
My next question is, at the bottom of the door on the inside you can see it has a lip I would say, well a section of that the rust dominated and when I sanding some of it, it just took those pieces off. I sad a product called 3M bondo self adhesive patch. Should I use that in that section then do some bondo over that/sand/primer/paint/clear?
