Heater box resto

There use to be a company called Full Circle Restoration that you could buy a paint kit to redo a heater box.
Have they gone out of busines ? If so does anyone have any recommendations on a method or paints to use on doing a box?
Used Full Circle kit before and liked the results.
Thanks
Mike

if your looking for a paint mixture to clean up a fiberglass strand heater box, go to resto ricks website and he details a formula to duplicate a new finish on one.

lemon Pledge will bring it back to life

Non air boxes. Ive done a very light glass bead the case.
Then a satin clear . It looks like new

Thanks everyone for your help will look into all of the mentioned ideas

Seen that done... looks very fresh, nice, and original.
