Here is the p-sheet for your MC161 (#8 on your list) :

P-Sheet

Look in the 'Mixing' section. Your MC161 is mixed with either the MH168 or MH169 at a ratio of 2:1 (2 parts MC161 to 1 part of either MH168 or MH169).

The MH products are your hardener. They are what make the MC cure.

MH167 is a fast cure
MH168 is a slow cure
MH169 is a very slow cure

That information is found in the 'MH161 High solids Urethane Clear' section.

The hardener you pick depends on the temp and your working speed plus whether or not you are doing a overall or panel. It's actually a judgement call on your part.

Normally, I use a fast cure during cool conditions and a slower cure during hot conditions.

 

Just use common sense with the respirators - adjust them for a nice tight fit. Remember, if you can smell the slightest trace of paint while you're working, it ain't a good thing!

IMO 55 degrees is a minumum while you're painting. In cold weather I always heat the garage up good (to 75 or 80 degrees) then shut the heat off while painting. (just about any type of heat system will blow dust around). Unless it's really cold and/or your garage is poorly insulated, it shouldn't fall below 55 untill a half hour or so after you're done. Unless your exhaust fan pulls it out. You may have to turn it on and off periodically if it's cold.

When painting after the heat is shut off, the bottom of the vehicle will cool down much faster than the higher parts. More likely to get runs down there.

In cold weather, static electricity builds up in a car body, and has no way to escape since the vehicle sits on rubber tires. It will draw dust into a paint job like a magnet. To prevent this, GROUND the body with a wire or chain or something - attach it to a water pipe or anything metal in the garage that is grounded.

When heating the garage, make sure open flames are out before you start shooting, especially close to the floor. (explosion hazard)

Your pricing estimate was pretty right on the button. I just purchased a gallon of OMNI MP172 Black and Catalyst (Qt) for 107.00. Now I get to see what it's going to look like on Bare metal....Wish me luck.
