3M cartridges

Hello, I’m new here and this is my first post.

I am painting an airplane (homebuilt) using Axalta AF400 series paint (AF403 packaged white to be specific) and I am pretty sure it contains isocyanates. I have been using a respirator with 3M 6003 cartridges, but have read a few things recently that claim that no cartridge is really adequate for isocyanates and that a forced fresh air respirator is needed. Anyone here more expert in the PPE field than me who can comment?

I have posed this question to my Axalta paint supplier, but haven’t received an answer. I suspect this may be a question they will dodge given liability concerns.

I looked at the Hobby Air systems and they aren’t super expensive. Looks like I could get one with a full hood for well under 1 AMU. AMU = Aviation Monetary Unit which is $1,000. Pilots and airplane owners use AMUs as it sounds better to tell your wife that something only cost 2 AMUs rather than 2 grand. 😂
