See that drain hole on the channel. I'd spray lots of Krown T-40 into it and since it creeps so well, it will seep out any opening.
Looking at my CR-V pic in post #36, that is 14 years going through serious winters where I live with plenty of salt. Of course, it is parked outside 365 days a year, so that might help instead of being in a heated garage (bad news). But I used Krown T-40 on it.
I got my rustproofing gun and wands from Dominion Sure Seal in Toronto. A heck of a lot better than the rustproofing gun I bought from Eastwood in 2000.

For a 9 year old car, that still looks bad.

to be fair, a Macan isn't really a Porsche.... the 911/Boxster/Cayman are very well built
one thing is for sure ... you better do SOMETHING.
Porsche does nothing special for rustproofing, its just another VAG box.

With my rustproofing gun, I use between 4 - 5 liters on my Acura RDX the first time and subsequent years I use 4 at the most. Of course about a liter of that is on me.
I assume they used Krown T-40.

I had my Tahoe treated at Krown this week. They laid it on pretty thick. I had iffy brakes for a while. I'm leaving it on the street for a week.

My son came over last night and was telling me about a Sierra truck he was helping a buddy with at the shop. They were removing rust protection so they could sandblast and respray. he said the rust protection was so thick it had almost hardened, and when they peeled it back the metal underneath was completely gone, the rust protection was sealing in water that couldn t escape.. some days you just can't win ...

I'm planning to drive my new-to-me 996 through the Toronto winter, and I've been going back and forth about rustproofing. Car was reportedly never winter driven before, and it looks pretty good at the moment.
I've read that over the year, the underside can really "gunk up" as the rustproofing oil application traps dirt and debris, and can make access/repairs from the underside a real hassle. How much of a problem is this, really?
And some say the car doesn't need any rustproofing as long as I give the underside a good regular wash, but I'm not too sure about that.
My underground parking lot does have a car wash bay I can use whenever I want to hose down the car/prevent salt buildup, but that's about it.
Thoughts?

After doing some more research, I ended up going with HoneySeal undercoating in Oakville.
They’re fairly new to the market compared to something established like Krown, but I trust the science they’re based on. They’re also much more expensive in comparison, but I figured it was worth the premium, at least for me.
- They dry ice blast the underbody to get rid of any preexisting surface rust prior to application of their wax. Given that my car is 24+ years old I figured it’d be best to ‘start with a clean slate.’ I didn’t like the possibly of Krown being sprayed on top of any preexisting rust that may go unnoticed and continue to spread underneath.
- HoneySeal sprays on yellow-clear so you can still “see” whats underneath, whereas Krown sprays on opaque black. I don’t plan on selling the car anytime soon but if it ever came to that, I thought potential buyers might be put off with Krown thinking something could be hiding underneath.
- I read that you should expect Krown to “drip” on the garage floor for a couple of days. I park underground in a condo so that wouldn’t have worked. That being said, the dripping would indicate that Krown permeates through all crevices in your car, which you want for a complete protection. I trust that HoneySeal does as good of a job though without the mess.
Turns out my 996 was already in fantastic condition despite its age, hardly had any rust to begin with. Porsches really do seem to do a good job rustproofing from factory, and previous owners must have taken a good care of it.
