I have just put a big chip on me inner door frame, can I touch up the chip with 2k straight from the tin without hardener, I have plenty of time for it to go off!!!!
Yes, but it will dry rather than harden if you see what I mean. Even the tiniest bit of hardener would make it harden eventually, like filler.
It'll be like mine....solid. Doesn't keep well, I'm in the same position as you but 3 years or dings to go over.
