Re: How to CLEAN N.O.S. Fan Shroud ?????
 

Rat Pack and others, Last night,before I read your bronze wool post, I started working on ANOTHER less valuble good used small block 70 shroud. I took some well worn GRAY scotchbrite and the FRP(??) graphiti remover and this cleaned another masking tape area.....As this shroud had "heavier" scratches I then used 400,1000 & 1200 wet paper.....then some 3M rubbing compound and then some polishing glaze....anyway I have made the used small block one look much better, but a little hesitant to start in on the EXPENSIVE NOS Big Block 70 shroud....The rubbing compounds and polishes tend to smear and streak and its very difficult to get a NEW clean look ????? ........Thanks to all.....Chuck

How did you come out on the nos shroud,did you get the sticker off.If so what did you do.

Thanks

The last thing that I did with the NOS 70 Camaro B.B. fan shroud was to try a product called Goo Gone...which seems to be one of those citric based products.....It didnt help with that 20-30 year old tape residue....Its like that glue residue has impregnated itself right into the surface.....Seems like only thing that might work is to start with abrasives as I outlined above......and then it wont look NOS any longer.......I wish I could find a GOOD used one to restore and not have to screw around with the NOS one.......thanks, Chuck

I am like you I wouldn't want to screw it up either.From my experience grafitti removers seem to be a lot stronger than alcahol when used on plastic items and surfaces.It's like it actually melts a layer of the plastic,at least the ones I have used.I have found that denatured alcahol does not react to plastic like grafitti removers do.I know a painter that uses a rubber seal product also called oil and grease remover on plastic and metal items and it seems to work on cleaning up dried compounds after buffing a paint job.And that stuff can be hard to remove.I hope you are able to get the stuff off without any damage.I will keep asking people that I know to see if someone can come up with a solution.

Did you try a few days under water? The tape material unless petrified is water soluble and the shroud really isn't. Given enough time the water should soften up the tape enough that goo-gone or the like can remove it...

For somereason,it succeeds were others don't.

My $00.02, how about media blasting?

Re: How to CLEAN N.O.S. Fan Shroud ?????
 

Chuck,if I were you I would just throw that one out and find another NOS one !!!!!

I say put a big MOROSO sticker over the spot it will cover it up and look realy COOL to

Like Stefano, I quite routinely use media or glass and blast my shrouds. I use low pressure and start in an out of the way place until I get the pressure just right. I also use this on air conditioning dog houses with very little if any ill effect of the plastic.

I would not suggest this on a part being resold as an NOS but have no problem on a NOS piece destined for a restoration I am doing.
