Rusting bolt on front suspension strut - potential safety issue

[Reagle]

a few rainy weeks and there was water in it after all. Not as much, but it still does get in. Also standing water around the outside

What I did was to use a small plastic container that you can get at your local supermarket's olive bar. It's flexible enough to squeeze through the opening and I held it in place with some silicone glue. It fits totally over the strut - the pic shows it in my 2017S after 15 months - the bolt is like new!! For max protection you could squeeze another through the hole and place it over the first.

It seems even though almost every LEAF in a wet environment has this issue with water filling up the top strut tower area, we haven't heard of ANY vehicle having strut tower failure or rust eating through the bolt. Is it the time needed to do so (10 yrs+) or is the bolt possibly protected well enough in there? I still plan on using the diy olive bar cover though...

I've compared other strut tower designs to random cars, and the LEAF is rather peculiar with the tower hiding nearly under the corner of the windshield, while most other vehicles have the tower at least a few inches in front...and a bulge or flat surface around the bolt, rather than a deep depression in the LEAF.
