Water signs in the trunk

[Mario Hi]

Hi all ,

I had an issue with my amplifier cause water went inside the trunk and it looks like coroded almost all the circuits , gladly it could be repaired.

The think is that i've replaced the two white groomets , abut i didn't fix the issue.
If you look upwords in the trunk on the metal frame , i can see some dots , that are looking like some water/rust marks , a lot in the part where water went , and a few in the right side too , near the spot where the panels are getting together.

The thing is that i don't know exaclty how water went in that place , i was thinking it has to do with the windsheald , cause the seals are looking a little old , and they are having little missing spots but i don't know exactly how to replace those seals.

Can anyone help me or have advices that can work for me?
Thanks in advance.

You may need a new boot seal or treat the seal with rubber preservative to soften it up.
