Hi @FredWork,
I've spoken with Berger's team, who have reiterated what Eric said. If you've applied it too thick, then the best thing you can do is give it a few more days to see if it fully cures. During this time, isolate the area and ensure it is not walked on or driven on. If, after another few days, you don't see any improvement, it is likely that you will need to scrape it off and reapply or just leave it as is and repair it if issues happen in the future.
Unfortunately, if you are going to scrape it back, it is likely there will be some lippage between the two paint surfaces, but this can be reduced by lightly sanding the edges to reduce the sharpness of the transition.
If necessary, pop on some gloves and long protective clothing, then use a utility knife to cut around the area for removal. Once an outline has been made, use a metal paint scraper like this 100mm Sharp Edge Paint Scraper to remove the paint. You can then use a sanding sponge to dull the edge in the paint before applying a patch coat to this area. Just make sure to apply it in a thin coat, wait the 16 hours, then apply a second coat if necessary.
Let me know if you have any further questions.
Jacob
