These responses are similar to the catalyzed primer comments on the 3k thread. Some folks have problems, others chime in along the same line. Not saying they haven't had the problem, just saying that the experience of thousands of others is different. In the case of catalyzed primers and panel bonding, the pros in body shops, other paint facilities, and even the OEM plants have success everyday with these products. They have an economic interest in success/performance because they have warrantees issued.

The DIY guy has a greater chance for failure for any number of reasons. Getting help is more difficult because they are "small fry" to the sellers of the material, and they are less likely (which is also to say not always) to store and use the materials correctly without realizing their error. There is also the chance that the material is out of date, contaminated, or otherwise environmentaly adversely affected. When I had my shop, if I had a product performance issue I would have a knowledgable rep at my door in short order to determine cause and remediation......................that's part of the benefit of spending many thousands per month for product.
