Okay, yeah this is pretty much what I thought. And just to clarify I consider anything you'd buy at Home Depot, Lowes, etc., instead of an automotive paint supplier a "house paint." Long oil alkyds are pretty much a shoot it and forget paint that is autoxidative, or in simple terms it drys and cures with the surrounding air itself after shooting. Almost all the automotive paints in use work by a catalyst/hardener that is added so we don't depend on air temp.s, humidity, etc. for drying or curing although temperature is still a factor. If you had coolish and those temps. you will be extending the dry times by possibly a few days but it should continue to harden and cure. As for taking care of runs, I'd wait till that fingernail test barely dents it then go to a hard block with some 320 to 400 P sandpaper and see if it will block down. I would think you'd probably have to respray that panel because I just don't know how well this stuff is going to buff back up. I mean sure after sanding the runs down you could certainly give it a try. I'd probably be using something like 3M Super Duty compound on a twisted wool pad, but that's just me.
Oh, and that one link is just the MSDS sheets which are disclosures for shop safety. This is the P. sheet which outlines how the product is used/performs etc.....
http://www.homedepot.com/catalog/pdfIma ... ba83e4.pdfBased on that sheet I would consider that you should put on about 3 coats of it if you want durability. Those coats must have a minimum of 24 hours apart in good conditions. On the plus side that product does tolerate low temps. and high humidity better than most of these long oil paints.
