<div dir="ltr" data-setdir="false">PAPRs are good especially when someone has facial hair. The problem with isocyanate and respirator cartridges (including those that go on a PAPR) is that there is no indication when they stop filtering isocyanate out. Need to change the cartridges often enough to be effective. Can't leave cartridges sitting around exposed to contaminants and moisture which reduce their effectiveness. JoeB</div><div><br></div>

<div dir="ltr">Most of the two part urethane paints are hazardous like Imron. The hardener is isocyanate, which can cause severe allergic reactions when inhaled. Once allergic to it, a person can react to it with every exposure. Isocyanate is the chemical that was responsible for the deaths in the Bopal, India chemical disaster many years ago. Be sure to use a good tight fitting cartridge respirator when spraying these urethanes, but I think most safety instructions say to use a supplied air respirator. </div><div><br clear="none"></div>

POR 15. Depending on the color, the number changes. I think
15 is black. Gray is something else, maybe 10. Spray or
brush on. I've used Rustoleum as the touchup rattle spray
cans are perfectly matched to the quart cans, and you can get
it just about anywhere. POR products might be a little more
durable than Rustoleum. If the frame is bare metal, an epoxy
primer is a good start, but with POR I "think" you can skip
the primer. </span> </div>
