Re: '79 Starcraft SS 16 restoration
Paper masks are pretty much useless. While cured epoxy (plastic) is inert and not a health hazard, you still don't want to be inhaling plastic dust. The 3M half masks you can get from the box stores are fine for most tasks. Make sure to use pre-filters so you're not constantly changing out expensive vapor cartridges. Note that the main cartrige is usually an organic vapor cartridge and has a short life span once out of its packaging. As long as you're not using the mask to filter out vapors this is fine. The pre-filters are what you are really using to block the dust. Just keep in mind that if you need to use the mask in an application to block vapors, you will need to install a fresh set of the appropriate vapor cartridges.
I stopped using half masks and switched to a full face style. I wear hard contacts and with the full face mask I don't have to worry about stuff leaking in and getting in my eyes. I now use a MSA Ultra Twin.

Edit: Never, ever ever ever, spray epoxy or a two-part catalyzed glue or paint without a positive pressure respirator or supplied air and the proper training. Inhaling a catalyzed two-part product in aerosol form is pretty much guaranteed to shorten your life span. Spraying epoxy adhesives that have been atomized without the proper PPE and procedures can be fatal.

When I'm grinding the epoxy do I need a respirator and everything or is it going to be ok with a normal mask kinda like this one?

We do not recommend spraying epoxy products because the health and safety risks are enormous. As epoxy leaves a spray gun nozzle, it is reduced to tiny droplets (spray mist). You can easily inhale epoxy that is suspended in the air. It can cause extensive lung damage and other health problems.
The spray mist can settle on your skin, causing sensitization and allergic reactions. It can settle on your eyes, injuring them.Compared to other application methods, spraying increases the amount of hazardous volatile components released from the epoxy. Using solvents to thin the epoxy for spraying adds to the health and safety risks. These hazards are similar to those of any spray painting operation, involving both health and flammability concerns.
If you are determined to spray epoxy, control hazardous vapor and spray mist by using isolation and enclosure, such as a properly designed, ventilated and filtered spray booth. In any case, if you spray epoxy, you must use an air-supplied respirator and full-body protective clothing!
