Pre-softened pastes can be called like that as they have a semi solid consistency (pudding). Duragloss paste comes to mind, or for the older generations, Johnson Auto Pudding.
They sit peacefully in jar, but they can be applied via a spout. Unfortunately I have no experience with this stuff because its not available in Hungary, but I must tell you that one of my fave sealants is in fact the Turtle Wax Gloss Guard, which looks killer, and has a really impressive (easy 6 months) durability.
I'm absolutely not brandophile and TW can make world class products too. TWPUG, anyone?
