I was unaware that you could buy a fresh air system for less than $900 or $1000. I will look into that Neoterik system and will probably pick that or another affordable one up before my next paint project, or at the very least a full face 3M mask. I currently have a half mask 3M but the last time I painted I got very sick feeling afterwards. Its just not worth it to save a few bucks IMO.

thanks for all the replies.

I know it has been said befor, but the respirator manufatures exclusion of protection from isocyanates is a legal issue. They are not willing to liable themselves by saying their cartridges remove iso's, even though they will.

New activated carbon filter do provide protection to a point. If I was spraying in a totally enclosed non ventilated area I would be concerned about isocyanate exposure. In a properly ventilated booth half mask respirators with new organic vapor cartridges will give you adequate protection. I concur with the other safety suggestions about covering all exposed skin.

OK. So I am interested in opinions. I plan to paint my car myself (once the laughing has died down, I will continue).

I haven't designed it yet, but I intend to go with plastic sheet walls and ceiling in my 3 car garage. Air will be supplied from a furnace blower from a 2000 sq. ft. residential furnace. It will pressurize the booth with fresh air, well removed from the paint fumes. It will have a filter before and a filter after (probably cheapies). I am leaning toward cross-flow with the exit at the opposite end from the inlet. I am also leaning to a soaker hose on the floor. The car is a 41 Chevy 2 door sedan. I will probably paint it in pieces because of the nature of the fenders and such. I am thinking in this order: bare metal, etching epoxy, high build primer of some sort, filler if I can't get it straight enough by metal working, blocking, repeat primer and blocking until flat, epoxy sealer, bc, cc. Solid color (red) as I don't want to tackle anything fancy. Oh, the underneath. I am going to have the frame powder-coated. The floor will have an etching epoxy and red spray on truck bed liner. Depending on whether my rotisserie clears the ceiling or not, I may have to do this outside.

Half mask with new canisters, full mask, supplied air? Any other advise? It may be a while before I get this far, but I believe in planning ahead.

One more consideration when choosing a respirator is that it seems to me anyway that the full face designs are a lot harder to obtain and maintain a good seal. I have used both types for years for toxic metal fumes and for me anyway the half mask just seems to seal better. Not saying the full mask(cartridge type) does not work just something to think about and be aware of.

The full face mask also has a fit procedure that should be gone thru be a qualified tester. An inert gas with a pungent smell (smoke test) is done to test the quality of the seal on your face whether it be a half mask or a full face unit. The test is also for sizing the mask to your face as well as the sealing quality. This is done by holding you hands over the filters and breathing in to see how long the suction sticks to your face. Like has been stated before just going down to the local jobber and picking up a mask is not the only thing that needs to be done if you are to do this with the full intention of protecting yourself against chemical poisoning.

Really something like a Hobby Air system,I think around $400-500, is the best way to go. Think about it what does a gallon of PPG red base sell for? I would think that is cheap compared to what one spends on the material for a paint project so should'nt your health come first?

I saw nitrile gloves mentioned. Are the latex gloves like you use for fiberglass work not suitable for use with 2k paints?

Toyman: thanks for the tip on that Neoterik system!

The latex gloves aren't resistant to a lot of the chemicals and cleaners.

Thanks firechicken383. I'm trying to get ready for my first use of 2k paints and found this thread via a search. IMO, it ought to be a 'sticky' for all the good advice in it. I still start each day with a coughing spell due to a really stupid stunt of sanding bondo for 3 or 4 -full- days without a mask.

The nitrile gloves are a little tougher as well. Thinners will shrivel them up but won't eat thru them. I'm still looking for the one's they use the fork on for advertisement.
Harbor has a 100 count box cheap.

Yeah, believe me, the latex gloves are great for some stuff around the house, but definately not for painting, I tried them too for a little.

Also, our Walmart just started stocking these in a 100 count also for a little under $7.

It figures; I just ordered a box for 11.95 along with that Neoterik thing. Next somebody's gonna tell me they got that system for $99.95 somewhere.

grouch, what all options did you get with yours?

You'll have to let us know some product feedback when you use it.

I didn't order any options. It was just the single user system with a 50 ft. hose. However, "Len" from autobodystore.com emailed me today and pointed out that I didn't order any of the lens protectors. Since they are a lot cheaper than a replacement hood, I asked him to add some to my order.

That might not be very valuable feedback. I don't have anything to compare the system to, not even a respirator. I'll certainly give my impressions of it, but you'll have to keep in mind my almost total lack of experience with auto painting. (Someone who has never used a computer might give a glowing review of MS Windows while a long-time Mac user might call it a crude imitation and a Linux user might call it a crippled toy).

I call it a POS excuse for an operating system.

Tear away's are a MUST with a paint hood or full mask for that mater.
Paint itself isn't so bad but clear is a completly different story.
It will coat quickly and you need a new "windshield" almost after each coat when doing a complete or large panel. The overspray sticks to it like the glue it is.
