Hi there guys, I have an Alfa Romeo 75 that is a running restoration, I'm working my way around the car bit by bit. It's not going to be a show car or anything like that but I still like to make sure I do my best with every part I work on. I've seen some interesting posts on car restorations by people clearly very professional, lots of talk about good prep in removing the rust then applying Epoxy primer before a top coat such as Jotan 87a, but I don't tend to see any mention of Kurust or any other rust treatment and it seems noticeable by it's absence, I realise if its painted right away the Epoxy primer should take care of any flash rusting but what if there is a bit of time between that happening? I have a bottle and am happy to put it on but not if I'm actually doing more harm than good. I suppose what I'm trying to say is, are there any disadvantages to applying Kurust first, will it affect how well the primer attaches? is it just snake oil? I'm looking forward to hearing your thoughts on this.
