Whew, thanks for the words of support HOTRODPAINT, I definately need them
I was planning on using the urethane enamel finish (tougher coating?) and that is the one that does require a catalyst. But the same color in an acrylic lacquer finish does not use the catalyst.
But is the acrylic as good as the enamel (in durability anyway)? Maybe my idea that the urethane enamel is all that is based on just plain pooh?
'Cus if the acrylic is as good as urethanne and doesn't require expensive equipment, I'll go with the acrylic. But I also understand that if I use an acrylic Kandy, I need acrylic base coat too, is that right?
But if the Urethane is the way to go for durability of color/finish and a onetime exposure with a charcoal mask and HVLP gun won't make my arms fall off, then I'll stick to my guns and plow on!
So many questions! But I know that I'm going out on a limb by using Kandy (being the in-experienced painter that I am) and I'm just trying to get my arms around this stuff.
Many thanks for all your ideas, thoughts..........at least I'm enjoying the ride!

The thing to look for is isocyanates (typically diisocyanates) which are typical in many hardeners. I am using AU (Acrylic Urethane) and it is in there. I am using a charcoal mask and painting my one car outside with a light fan to direct fumes away from my face (within reason).
I've read some people can have a quick and severe reaction to isocyanate exposure. Usually begins with a scratchy and swolen throat. I breathed it for sure painting the bottom of my 32 earlier and experienced no problems. It's not so much mixing that is the issue, rather, when it becomes a mist during application that should be avoided injesting. From what I have researched long term exposure is much more of a concern. Like if you did this for a living like HRP!

wears a mask with an exterior air supply (Aqualung almost, but a lot newer) and hood!!! !!!
Wow things have really changed. Back in the mid 70's I used to paint motorcycles and cars with Dupont Imron in an unventilated paint bay with out even a mask let alone an air mask.
Probably why I am like I am today.
My painting days ended when I hung up my Binks model 7.Bob

Kitz, you're right, that's what Jon was talking about on the DVD! Isocyanates! Man that sounds bad! I hadn't thought about covering up more skin, though sometimes that is tough to do down here! I'll check out a nice white, light shirt from back in my shirt and tie days, I think I've got one or two around. Don't know if they still fit, but there is alway the Ross store!
Thanks Brian! That is what I've been thinking about, but am glad to hear that some other person (still alive) has a similar view!
Mopar, do they still make Imron? The first time I ever saw that it was on a camero, as red as could be! Folks said it was an aviation paint and was tougher than nails...is it still around? You should see what we used to break down asphalt samples back in the 70's...super bad!
OK, it looks like the opinion is it won't kill me so I'll be careful and make sure my HVLP isn't misting.
But a question remains, which is better, acrylic or urethane enamel?
Thanks again for all the help!...at least I'm enjoying the ride!
I saw last night on fb about John. The world sure lost a great one. I'm going to miss his humor, advice, and perspective from another portion of the world. Rest in Peace Johnboy.
