Hey everyone,

New to the forum and wondered if anyone could help?

I have a customer that I am doing some work for with building custom cabinets and restoring stairs etc.

They have asked me to look at the windows. Basically they have had new aluminium windows install but they keep weeping water in the winter. They are several cats of paint over them. I have tried using my Mirka sander and basic paint striper but nothing. Can anyone recommend anything. I feel like I am going crazy.

Many thanks in advance.
