Brush painted instead of sprayed

So.... I'll address the brushing question because my initial comment was off target. Yes you probably can brush paint.

The original question was: " has anyone had success with brush painting, the gloss Black, rather than spraying".

Not sure how a list of favourite rattle cans fits in.

I use rustoleum enamel in a can too for touch up items on my frame. I use a small brush and like said, put it on as thick as possible without running. Re: the Valspar enamel in a spray can, I used that on my oil tank and it's been quite durable. I was happy with it and how it went on.

If you brush, try hardener,it really helps flow and it gets real hard .

I have never seen enamel hardener. Can you tell me where you buy it. I would like to try it.

Be very very careful with that stuff.
If it contains isocyanate, then a breather mask/filter isn't enough,
you need a proper air supply system - from outside.

Think Bhopal...

I think its OK when brushing the stuff, it is available in hardware stores in the USA

The toxic warnings on that can are pretty dire !

Googling that product reveals it does indeed contain isocyanate.
Don't breathe the vapors, that stuff can be deadly.

there are no "vapors" when brushing it. Just don't stick the brush up your nose :mrgreen:

I just brush painted an old battery carrier, using common ole garden furniture (?) enamel.
I made sure I was upwind of it, turps fumes and all that.....

There is no safe level of that isocyanate stuff - even a filter mask/respirator won't remove it.
YOU may be totally immune to it, but other folks need to take heed.....

Must remember to never use superglue or gorilla glue again. You can smell them too but no dire warnings on labels.

Iso's come in many forms, and in combinations with other stuff, some more toxic than others...
If you read the safety data sheets, folks might be a lot more careful with these things !

The strength of common superglue was reduced somewhat a good while back - now it only contains a mere trace.
Too many good parents were putting "drops" in childrens eyes, ears, nose, etc !!
And the good stuff is almost impossible to remove, and reacts with almost violent heat.
There are all sorts of grades and strengths.

As others have suggested, although the MSDS sheet does not specifically say it contains isocyanate, there is a cautionary statement in the body of the MSDS stating "Overexposures may cause certain individuals to develop isocyanate sensitization which causes a reaction in isocyanates below the TLV". So be careful. All isocyanates are not equally harmful, as their toxicity relates primarily to their vapor pressure. The isocyanate involved in the Bhopal incident was an extremely volatile molecule - methyl isocyanate, thus the devastating consequences. In paint, coatings and adhesive formulations isocyanates are often reacted with larger molecules in order to reduce their vapor pressure and hence there toxicity. Gorilla Glue and Elmer's polyurethane analog are good examples of common isocyanate-containing systems having very low vapor pressure. However, if there is isocyanate present, there is always the chance of becoming sensitized regardless of the volatility. And of course, if you read the MSDS, simply the solvents present in any like paint formulation is enough to scare you into never using solvent-based paint again.

I was a little surprised to see the statement on the MSDS sheet regarding isocyanates because I would have thought that an enamel hardener would simply be some soluble form of cobalt or manganese in very low concentration, which are common catalysts employed for accelerating the cure of drying oils. Perhaps the hardener is not even intended for a drying oil system, but perhaps a polyurethane instead.

A mere trace of what?

Superness ...

Super. Created by the American military to close battle wounds up but fast ,then helicopter evacuation back to behind lines surgery. Goes brittle so can't see it in Norton use.

Well, not really, although an early medical use was in the war in Viet Nam.

The link above to the MSDS for the subject hardener referenced a 2005 version of the MSDS. I found a 2015 version that does in fact show isocyanate content present in this product.

Product Code 018.0004625.003
Product Name VALSPAR ENAMEL HARDENER 6HP
