Assembly Bastuck Complete system

Hey guys, I’ve got my Bastuck completely set up now (it’s now in the trunk). I’ll have to drive over the pit next door with a buddy and look at it. If I could do it together with my buddy as a helper, that saves with 100€ and I’m pretty close to cash through the plant rims and other things… Now I hope for your help, can you give with tips? 1. How do I solve the rusty places best? I can imagine the rust solver alone ni 2. What do I need for tools? Rubber hammer? I don’t want to beat the system to pulp! Is it stainless steel but oki… 3. Do you think you have to fix it after a few days again after coming back??? to the claws etc.? 4. Any tips?? Would be really great! Greetings Chris PS: Have already exchanged ESD from my old Essi but that’s also everything! And I know that I need so assembly paste for the exhaust.
