[Fot] Frame paint

 PAPRs are good especially when someone has facial hair.  The problem with isocyanate and respirator cartridges (including those that go on a PAPR) is that there is no indication when they stop filtering isocyanate out.  Need to change the cartridges often enough to be effective.  Can't leave cartridges sitting around exposed to contaminants and moisture which reduce their effectiveness.  JoeB

  This is good advice!!!
I almost killed myself with I think Dupont Chroma 1 or some such in 97, still get a reaction when I get a whiff of it.Now I use a 3M PAPR, even when mixing & cleaning up.And of course y'all know that no mask/filter system will work if one has a lot of facial hair...

  Most of the two part urethane paints are hazardous like Imron.  The hardener is isocyanate, which can cause severe allergic reactions when inhaled.  Once allergic to it, a person can react to it with every exposure.  Isocyanate is the chemical that was responsible for the deaths in the Bopal, India chemical disaster many years ago.  Be sure to use a good tight fitting cartridge respirator when spraying these urethanes, but I think most safety instructions say to use a supplied air respirator.

  Hi Joe.  When I bought the Imron for my car in 1980, the guy wouldn't sell it to me unless I also bought the respirator he recommended!  Strong stuff.

 In the 70s we were painting John Deere Tractors in DuPont Imron. What wasn’t done by robots was done by painters in HazMat Suits.

 I don't know if it is even still available, but years ago I painted the frame on my race car with Dupont Imron.  It was the most durable paint available at the time, and my experience reflected that.  The stuff is very toxic, so you must use a very good respirator.

Grey will show cracks better than black.  POR is the first thing that came to mind for me, but it's been YEARS since I used it.

Cheers, Tony

 I'd suggest POR 15.  Depending on the color, the number changes.  I think 15 is black.  Gray is something else, maybe 10.  Spray or brush on.  I've used Rustoleum as the touchup rattle spray cans are perfectly matched to the quart cans, and you can get it just about anywhere.  POR products might be a little more durable than Rustoleum.  If the frame is bare metal, an epoxy primer is a good start, but with POR I "think" you can skip the primer.     Dave H.         On 09/27/2023 5:55 PM PDT McKearn McKearn via Fot <fot at autox.team.net> wrote:            Hi All. 
    It's been a long time since I've painted a frame and I'm just wondering what the latest / greatest thing to use is for a race car frame ? It's already sand blasted if that matters..      Thanks.  P.J.   _______________________________________________
