Now that it's finally getting warm out, at least where I live (MN), what have you guys done to reduce the cabin heat coming from the front?  It doesn't seem like much comes up from the seats and the engine.  I have a 2023 UFORCE 1000 and the amount of heat sucks! 

I have a UF600.  I plugged all the holes in the firewall with closed cell foam primarily to minimize dust infiltration.  I put sound deadening sheets on most of the plastic on the engine side.  When I touch the uncovered plastic, it is significantly hotter than the sheet covered plastic.  I think it would be a PITB to cut and stick this stuff to the firewall, but it might be an option.
