Fan Shroud Restoration

[CamarosRus]

What I have done to restore several shrouds and A/C boxes is strip all
paint and grease and undercoating off them first. Then sand out any
scratches with appropriate paper and grit and hopefully get most of the
scratches out. Sand with nothing rougher than 400 grit paper before
the next step. Then I lightly blast the plastic with fine glass beads
to give the entire piece an even look. This will really make the part
look like heck, but the next step brings back the color very nicely.
Apply a coat of polyurethane clear satin to the part and let that
cure. I continue with coats of polyurethane clear to fill the
remaining imperfections while sanding significantly in between coats.
This is a long and boring process, but eventually you will get the
imperfections filled in. Finally finish with a coat of satin
polyurethane or if you prefer a flat urethane, depending on your taste
for shine. This method really allows the original plastic mold marks
to show through and doesn't give that just painted "black" look. I
have had no adhesion problems and used MinWax polyurethane spray bomb
available at Home Depot or similar stores.
