Sometimes you just stop and think about the moments of joy rust brings⌠Here are a few quotes from my diary:
âChanging the subframe in a gravel yard made me consider getting a FĂśli cardâŚâ
âThe job rocks, as long as the slag flies somewhere other than up my sleeve.â
âHeh, side skirt plastics⌠Probably shouldnât have taken these off.â
Proceed to put them back with a self-drilling screws
Professional rust repairs are expensive, including preparations and painting, so in my own delusion, I truly feel that with my tiny proactive DIY acts, I will save a few pennies. My intention is therefore to keep the metals hard and the inspector soft for a long time, even though I really enjoy welding.
⢠Waxes and coatings. In summer, the sun damages the paint surface, and in winter, salt causes trouble. Itâs good to wash and protect the vehicle regularly.
⢠Stone chips. In my opinion, these should only be found on the hood, fenders, and sills. Since weâve come this far from biblical times, your vehicleâs dealer should have dab-on touch-up paints by color code. There are also generic paints available if the visual presentation doesnât matter that much â covering bare metal is still the most important point. This procedure can be done once a year, for example.
⢠When changing winter wheels to summer ones, it might be a good idea to remove the inner fender liners at the same time. This allows you to nicely rinse away the winter grime from behind the inner fenders. The removal itself isnât a difficult task, but this procedure, including the tire change, might take a bit longer than a basic F1 pit stop.
⢠Cavity waxes/rustproofing agents. I wonât bother linking, but on YouTube, you can find, for example, NosSamâs âKotelosuoja Testi 2023â (Cavity Protection Test 2023) video, which proves that products available even in department stores significantly slow down the destruction of rusted metal. Iâve personally used Biltemaâs wax-based ones because I feel they donât trap moisture against the metal, unlike some of the marketâs thickest sealants might do.
Rusting can also start from inside the body, so cavity waxes can be sprayed into the sills, for example, through the holes of the bodyâs plastic plugs. Spray guns that connect to compressed air are also quite affordably available. You can even attach a hose to them, which allows you to reach tight spots nicely.
The pockets of the shock absorbers have relatively challenging shaped metal to work on, so itâs good to poke some prevention in there too. From behind the inner fender liners, I treat the wheel arches. A one-way ticket to Africa (i.e., scrapping the car) is usually issued due to a rusted rear crossmember, so itâs good to pay attention to the rear end as well. With the remaining gunk, you can even douse the subframe under the engine. These cannot be welded to make them strong again; when they rust through, they must be replaced with new ones.
The liquids, guns, and waxes can be bought from a store for less than a hundred euros at their cheapest.
By the way, hereâs a pretty good promotional video for rust protection that I once saw on the TV at the inspection station.
If youâve just happened to bring home some cash from the stock market and are very attached to your own car, then itâs nice to take the vehicle to a professional â it certainly wonât harm the carâs resale value; quite the opposite.
