Fan Shroud Restoration

[COPO 70 RS/Z28]

I wonder if this would work, it sometimes can help for scratches on the plastic of quads. Use a propane torch and wave it across the scratch area (quickly) for a few waves and then rub the scratch. We have used this method to reduce the scratching on the fenders of our quad racers.

I'm not sure about trying this on rare part !!!!!


Maybe someone else has tried this. Also REGULAR CREST toothpaste is used as a polishing compound for the plastic pieces on the quad racers. It has to be regular old crest.

Not recommending this for rare parts but it does work on the plastic quad racer parts.

Anyone else tried these techniques

The Crest should work well in the "cavaties" on the fan shroud

Wise guy, eh?!

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.

Sam,you want to wetsand it with very high grits of sandpaper and it will make it new again. practice on an old one that you do not care about but start out around 1500 grit. that is how i did mine and it turned out nice. alot of elbow grease will make it look great!

Good stuff guys. I've got plenty of the e-grease handy. I'll post my results over at "Roof Deuce Restoration".

Thanks and am open to any other suggestions.

Do not do this for a fan shroud! Your method works well on ATV fenders because the are made of polyethylene which when heated will act waxy and fill in flaws. Fan shrouds are made of a different material that will burn when heated.

Here's what happens when good shrouds go bad...they burn. (Carb fire gone wild)

I'd agree with Chad's recommendations. The 1500 up to 2500 grit does a great job and I've even used 0000 steel wool with some decent results on the plastic inner fenders. Then some ultra-fine polishing compound to finish up. The key ingredient in all these projects is patience and elbow grease.
