We bought this door:
I've primed it using Zinsser and then gave it 2 coats of Behr Marquee Exterior.
Looks great. Alas, 24 hours later, I can take my fingernail and scrape of the paint.
It's been a bit humid/rainy. Do I just need to give it more time for the paint to fully harden? Or did I do something wrong with this fiberglass door?
Another day and the problem remains. I can confirm it's the paint. The paint can be scraped off with a fingernail, but the primer stays.
I'll give it another day or so (it's been humid) and hopefully it fully 'cures'. But if not, do I have options short of stripping the entire door? Is there any sort of top-coat I could apply to give it a stronger surface?
