I have my entire HVAC box out of the car and trying to restore to new to go as long as possible before doing this PITA job again.
My questions are on safety of various adhesives, foams and paint to use inside the box.
I noticed there is a steel cross support in the blower motor area of the HVAC box that is all rusty. Can I safely paint that with self etching primer and topcoat? The can says not to apply to surfaces that exceed 200 F. I think the coolant gets about that hot, but can't imagine the air would... Ok to paint that steel to avoid future rust?
Also, I want to replace the foam on the door by the blower as well (damn mice), but wondered if I have to use a specific adhesive that would stand up to heat/ not degrade. I'm planning on using Home Depot weather stripping foam. Please let me know if anyone knows of something better.
Finally, there was a foam gasket around the evaporator that I plan to reuse. What adhesive is safe to attach to the evaporator?
Heater core did not come with foam i see in some youtube videos. Do people go without or again add some specific foam/adhesive from Home Depot that withstands heat?
Appreciate any advice.
