A/C heater core box restoration question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

An original heater core box inside the cab. I cleaned it but you can still see the white-ish marks from ppl hitting it with their feet. Can this be polished up to look new again? What products have you used? I really don't want to paint it.

Also when it's wet all the scratches appear to dissappear. . Just not when it's dry

I used a satin clear.

I used a very fine sandpaper to wet sand on a very faded box, took some time on the nooks and crannies then clear coated over the natural surface. Maybe not a hundred percent factory looking dude to the clear coating, it's very clean and looks good very close to original, i also think I used a satin clear

Good idea. I was thinking clean/polish rather than anything abrasive. Mine looks like that too

Sanded my box down to 400 grit and applied clear. All that is is needed. Results can be seen in my build thread.
