I don't know about KILZ, but I have had many years' experience with Lanco products on my boats.
I've used their primers on three houses.
The products I've used were all excellent in both application and durability.
Lanco makes various products in various stages at various places. Among them are Brazil, Venezuela and even PR at one time.
Their polyurethane marine varnish is far superior to anything I found in Europe or the States. Dunno about finish paints.
