Need respirator recommendations

I’m getting ready to primer some areas of my car and I want to buy a new respirator that will be good for epoxy and urethane. I have an old 3M that’s ok, but I want something better. I’m not afraid to spend a little money, but I want something I can easily get cartridges and parts for. Any suggestions? I there are a lot of opinions on this, but I know there are a lot of guys on FABO with much experience than I have. Thanks!

This is what I bought. Just bear in mind that the charcoal filter cartridges only provide protection against isocyanates (clear and urethane hardeners) for 30 mins or so from first exposure. Obviously fresh air respirator is best, but if you don't have a need for it often they are pretty expensive.
