I've got my body off the frame and am hoping to brush on some undercoating this winter. There are a couple low temperature epoxies that pop up on google: https://www.epoxy.com/899cold.aspxhttps://protective.sherwin-williams.com/detail.jsp?A=sku-26767%3Aproduct-7006The garage isn't heated, or substantially insulated and I'm not sure how effective heaters will be... maybe if i get several propane tank heaters? Expecting daily lows in the teens/20s and highs in the 30s/40s for the next few months.

Even if you do find a product that will work, you'll have to keep the temp up to at least 50F. You need to VENTILATE (see this post), and ventilation takes lots of heat to offset the cold air coming in.

If you can't wait, build a "tent" around subject, heat inside tent, wear breathing gear.
We don't know if you are painting a bus or a cooper mini or just parts. Makes a big difference.
Even if you are able to paint in a "warm" tent, the paint will be curing for a few days at freezing temps overnight. NOT GOOD.

epoxy.com did not respond to my questions about using their low temp primer as a truck undercoating.
I can only speculate that it probably isn't as flexible as something meant for metal.
So I decided to get a bunch of heaters and some tried/true SPI epoxy primer.

Google "The perfect paint job" by SPI.

You don't just heat up the space and go to work. It may take hours for them to reach temperature, so point being, use a laser thermometer to be sure paint and sheet metal is up to temps before you start painting. | | |
