Karl, the stuff I use is sold as Pledge Revive It here in the UK - I think I ordered it from that South American river. It’s the old Kleer in a new label, it doesn’t need thinning to spray, dries clear, and is my go-to to seal decals and act as a base for pin-washes. Other formulations are sold under the Kleer and Pledge banners, but are not the same!
