There is a refrigerant sealant that is used in commercial/residential applications and not the automotive for some reason,(forget the name) it is not cheap, about $75.00 Canadian, but this stuff will seal any small leaks and lasts. I used it on my 94 GP two years ago and the system is still tight. You should be able to buy this at any heating, cooling and air conditioning supplier.
