Got a request to paint some brackets for a barn that is being converted to a wedding hall/rental space. To say this stuff dries fast is a serious understatement. 10 mins after spraying it passed a heavy scratch test. I had to test it to make sure it will somewhat survive when they put the bolts in that I am painting as well. So far fun job.
43 brackets(25 lbs a piece )
300 bolts
300 nuts

MSDS shows it's mostly naphtha based with a little toluene and xylene and trace amounts of various alcohols.

Yeah, it's going to dry extremely fast.
Good thing you're in such an open space too, them fumes are highly toxic and intoxicating...not to mention explosive in larger concentrations.

Ithinned it 50/50. It was like spraying lysol. The stuff can be thinned 125%. So I bought 1 gallon and 1 gal lac thinner and made up 2 gals. Works awesome had to scratch with a siding nail to hurt it. It's great for wood but only comes black or white and can not be tinted.

I used to sell that product. It is a Sherwin Williams product from their chemical coatings division. Actually been around a long time. From the 60's at least. They have an acrylic metal lacquer in that line that is pretty damn good on car rims. I wouldn't get too caught up in it though as the VOC's are really high in that product line.

The opex clear can be tinted. ;) Just saying.

We use it to make a copper tone. Works awesome on metal. Solid stuff, some automotive places use it as a clear coat.
the clear acrylic metal lacquer is also great for recoating exterior brass and copper fixtures and what not.

It comes in a pre-packaged white and black. They also have a clear that can be custom tinted with powders.

Does it make a difference? Not really. Think of it like wood work that has a tinted (toned) layer on it. Just a clear coat with a color added in.

If the job calls for just black and the out-of-the-can stuff is what they want/works. Use it, it'll be easier to do touchups on. You won't have to remember the ratio, look it up, etc.
