Hello dear community I once sat down at the end of the week and made my car really winterproof. since the sweet from next year winter car should be equipped also. what do you do or should you pay attention to everything before the winter at nem 80er b4? so I have frost protection in the cool water, windscreen wiper system filled up. car battery refilled. what cost me about 10h was my underfloor. here I freed all underfloor part 1 from rust – jegleche n rust with the felx removed 2. with long-term rustproof paint painted wheel slope with rustproof paint front slope with rustproof paint rear 3. underfloor protection 3ply pinned over -on all metallic parts (wheel suspension, side skirts, wheel boxes, brake lines) 4. cavity preservation in any intervening rooms 5. all rubber seals or axle cuffs lubricated with graphite grease are otherwise any childhood diseases or similar?
