Will painting respirators protect one from the COVID-19 virus?

Looks like painting masks are at least P95 rated = same as N95 or FFP2 but with oil resistance.
If you have the luxury of selection you really want FFP3, P100 or N100.

Silicone rubber facepiece seals lot better than single-use mask/respirator but as mentioned keeping the rubber facepiece kosher is another matter.

Put on before you encounter contaminated areas and take off only after you have enough time to disinfect it before next use.  Overnight in +70cel sauna or electric oven should take care of even most stubborn coronaviruses.

OK... can these masks take the 70°C punishment without getting damaged though?

"probably"
I wouldn't worry about the mask itself, filter element is bigger question but I'm fairly confident that mild heat is the best option compared to others (steaming, boiling, gamma ray, soaking in alcohol)
Just my 0.01cents. In case I happen to be wrong I'll offer my condolences and 100% money-back refund.
Electro Detective:
Any cheap and serious masks I have are for real breathing hazards, like painting, plaster dust, yard/garden blowouts, compressed air tool stink, welding and soldering up close etc etc
and let's not forget eye and ear protection in on the deal too

Anything beyond that calls for a proper self contained breathing rig coupled to a hazardous waste outfit, or NASA astro suit, END OF STORY, to keep real nasties and aliens out. 

I'm not fooling myself to believe if I walk around with a mask like all the clueless idiots I see breathing back their own moist exhales  ::)  +  :palm:
that it's going to keep out any real deal virus that will seep into a body one way or the other, sooner or later,

or NEVER at all if this turns out to be yet ANOTHER global panic bandwagon resulting in financially shafting battling families and struggling businesses even more.

Time will tell either way, and the clock is ticking..  :popcorn:

in the meantime, if I need to protect my airways from the occasional black smoke belching car, truck or bus, or billowing high rise dog box apartment construction dust,
a pocketed tissue, hanky or clean rag is a good enough short term PROVEN fix, cheap and portable     :clap:

and good enough to play the corona game too, whilst watching sickening hoarders empty the shelves, keeping a straight 'normal shopper' face  :--  :--     = (expletive) idiots  >:(
