Narrative:
I was sent to ZZZ to assist air carrier with the vendor final walkaround inspection. All discrepancies were documented on the final walkaround worksheet. My understanding is that all items written are then evaluated and xfered to non routines to be worked. While inspecting the cockpit I noted that maintenance contractor had painted over both sliding window frames sealant, but had not addressed the poor workmanship of the sealant. The sealant along the forward ends was rough and uneven. It appeared the original sealant wasn't given the proper amount of time to cure prior to use. Subsequent pressurization had only aggravated matters.
