I've seen plenty of posts using this product and would assume that if its not safe for a UDS, that would be well documented here. However, I'm really concerned about off gassing during the cook. I don't want my guests getting ill from my modded rig! Any input would be appreciated
I pulled this from another post here on the BBQB: The Permetex site said this:
" When heated to temperatures above 300 degrees F. in the presence of air, this product can form formaldehyde vapors. Formaldehyde is a potential cancer hazard and a known skin and respiratorysensitizer. Safe handling conditions may be maintained by keeping vapor concentrations below the OSHA permissible limit for formaldehyde"
