Sealant Peeling From Around Lenses

[gapi]

I noticed this when I removed them to do a re-installation. My current was not very good.
I flakes at the slightest touch.
So....... I am getting no errors (yet) and am in warranty if it applies but would just assume re-coat them if advised the right stuff to keep my warranty.
The stuff looks like regular RVT and I have some Permatex ultra black and small brushes.

I am an industrial maintenance technician mechanical of more years than I care to reveal. I can handle it but want to touch base first.

Thanks
