Johnny,
Just a quick add on here…
Using any paint below 40 is risky. But you got to do what you got to do huh? Suggest at a bare minimum to use a paint that meets the federal spec TTP-1952-E TYPE II like Prostripe MX. The TYPE II is important as it means the paint is designed “For use under adverse conditions”. Beyond that if you can find a local paint made with Dow’s Fastrack XSR (I think Sherwin has one) resin. It is designed for temps that are 35 degrees and rising.
Things to consider is surface temp (sometimes varies from ambient) and humdity (a killer at any temperature), sunlight (it conducts and renews heat to the surface) and wind (the chill factor). Check out DAFscale.com. You are certainly invited to my NPE presentation covering weather relation to Sealing and Striping.
