Windshield escutcheon plates

[Whaler]

Hi

My car is in the shop getting painted. I was with the painter yesterday and we were trial fitting the windshield again as he suspected we might have to open up the slots in the body a little more ( he saw evidence of a crack at one slot)

Turns out the fit was good, plenty of room and suspects the builder had probably let the windshield move on its own weight while trying to fit it alone. Therefore cracking the body at the slot as it slipped or fell backward.

Anyhow here's the question.

I had the chrome cover plates with the hardware for him to use if req'd. He was surprised that I had no rubber seal or a grommet to go around the posts and under these plates. I never really thought about it until now but do they supply these usually?
I think a rubber seal can be made easily and he also suggested black silicon to. His concern was keeping water out when you wash the car.

All I had was the chrome plates with my delivered kit.....no seals.

Anyone else worry about this and what did you do
