Hey guys, need an advice as I have spent way too much time on this problem already. I am the most anal person when it comes to personal big ticket purchases and itheir maintenance, so I need a thorough reply based on some sort of a genuine experience. Trust me, I sued search function to its extend.
After googling and reading and watching and asking, I have narrowed down two shops to get my new car to for rust proofing: Krown and Corrosion Free (Robinson Automotive). And, at this particular point, I am leaning towards Corrosion Free and this is why:
1) No holes drilled (in most cases). Big thing as I am not looking forward to holes being drilled in my brand new car.
2) Warranty covers surface rust. Which is a big factor because that's the type of rust M3 gets most often.
3) Doesn't drip
4) needs to be reapplied every 18 month instead of Krown's 12 months.
5) Canadian military uses it (doesn't really matter, but thought it was a nice statistic).
It is a bit more expensive than Krown, but the fact that it has a longer time-frame between applications makes it the same price in a long run.
On paper, the advantages of Corrosion Free far outweigh those of Krowns. Thus my question is, why do most people still go to Krown? Poor marketing on CF part or am I missing something?
Will be keeping the car for 5 years, want to see no rust originating. 2015 3 hatch.
Thanks
