After repairing cracks in the deck, I painted them with Awlgrip topcoat base. Naively, I haven’t added any other parts to it (converter, accelerator, etc.) Not surprisingly, it never cured and stayed soft to touch even after several weeks. Ended up having to remove it in order to do it properly. Doing it mechanically proved to be a real bitch – sandpaper just stuck to it – so we finally found a thinner/reducer and were able to wipe it all off. Whew…
