    We got a surprise rain about 4 hours after I sprayed a bunch of metal posts and channels with one:

    In the next morning, I can see bubbles appearing on some of the items I painted. Those definitely need scraping and re-priming. However, some of the items does not show bubbles under primer.

    The question is whether to scrape the primer and re-prime all of it, or somehow check which ones actually need re-priming?

    The guy at the SW store can probably answer best, but i think you spot-sand and spot-prime the affected areas.

    Yes, I think that is what I will do.

    OP, It wasn't dry enough.
