A Dec. 14, 2012 news item on Azonano has announced a new 3M product,

3M today introduced a new product designed using the latest technology in wall repair, making it possible to paint without priming when patching a wall. 3M™ Patch Plus Primer is the only product on the market that uses nanotechnology to create a quick-drying, strong, even patch in just one easy step.

..

The product was specially designed to address common challenges pro-painters and DIYers frequently face with wall repair such as shrinking, cracking and changes in paint sheen. Engineered nanoparticles create a primer-like film on the surface, allowing the repair to be virtually invisible under dried paint, for professional-looking results without having to prime. Square packaging was developed to easily accommodate a three-inch putty knife, and the product’s lid was created to be easier to open than traditional spackling products that require a putty knife to remove the lid.

Unexpectedly, there is no listing for the product on 3M’s DIY (do-it-yourself) website nor in its product catalog so I could find no additional details about the product other than those in the news item (which was originated by this Dec. 13, 2012 3M news release on BusinessWire).
