Heater box/Evaporator box refinishing

Ideas and pics for heater box refinishing please. I think I will just prime and paint it when I get my truck painted in a few weeks.

Re: Heater box/Evaporator box refinishing

I was going to have mine rhino-lined ... but ended up just using a soft wire wheel and putting it back on...

Re: Heater box/Evaporator box refinishing

I just did mine... new heater core, new gaskets, etc. Check the heater resistor while you have it out, it's easier to get at.

I wound up sanding the scratches out of it and painting it with Eastwood Underhood Black.

Here's a tip: the heater core is held in by two thick wire supports that bolt in. My core was an aftermarket replacement that didn't fit tightly, so I slit a piece of fuel line lengthwise and slid it over those wires before boltiong it all back in. This held it in place without any movement and should prevent a lot of rattles in the future.

I washed/ cleaned off dirt etc rubbed Mastercoat black (this is like POR15 but I like it better) over rough surface this made it look like what I thought was original...

Re: Heater box/Evaporator box refinishing

I had a broken heat box in my 70, I fixed the crack with fiberglass then sprayed it with a texture spray made by Plasticoat, it looks like bed liner but a little more coarse. I then sprayed it satin black. No pics but it really looked nice. I used the same stuff on the interior heater box on my 69 and 72. In the past I have coated similar items with a heavy coat of paint then dusted the wet paint with sand then another coat of paint. It really works well.

Check out this thread where they used Gibbs oil to freshen up the box.

Re: Heater box/Evaporator box refinishing

In both of my restorations, I took the box out and when no one was home gave it a scrub in the bath tub . After drying it I purchased some cast blast or similar cast iron colored paint (it is actually pretty close to the original finish on the box) sprayed the box , replaced the evap cores, used stainless screws to bolt back together new gaskets etc.
