I had a leak and got a new rad, I personaly wouldn't use a rad seal type product.
A good way of finding a leak is to look for steam when the engine is hot, preferably on a cold evening with a torch. Maybe you can then be sure if its the coolant rad or the aircon rad.

This is exactly my symptom apart from ive noticed the coolant is very slowly going down, also my cabin is steaming up in the last few days. Has anyone found out if it is aircon or rad...? And what to do?
