Fan Shroud
« on: July 27, 2013, 09:29:06 AM »
My original GM fan shroud was painted by a previous owner, and I have been trying various methods of removing paint without damaging the plastic. So far, the best method is to use a heat gun on a low setting, with a plastic scraper. However, this is taking forever and I have been offered an easy option - another fan shroud off a 69 small block car. My only issue is that my shroud has the part number 3938615 and the one on offer has 3938-615. I'm wondering if the one with the 'dash' in the part number is a reproduction - can anyone confirm?

Try the stripper that's good for fiberglass - it shouldn't bother the ABS parts. Test it on a small area first, just to be sure. I have stripped fiberglass and urethane using the aircraft-type stripper, both worked very well and did not damage the base materials at all. If you scrape vintage plastic, it's gonna show when it's clean.

Last swap meet shroud (69 SB) that I found, really grungy, cleaned up to the point it looks NOS by using a soft brush, dish washing detergent, followed by a liberal coat of Detailer's Advantage - after the part dried off, it looks better than the NOS one I have in inventory. $5.00 shroud, by the way -

Thanks for the suggestions Steve - I have already tried various other methods, but found the heat gun delivers the best result. I may still give the fiberglass stripper a try though, was told it is likely too harsh, but could try a small area that won't be seen once installed.
My query was just over the part number, as I have never before seen a genuine GM 7-digit part number with a dash in it.

Use the organic stuff in the bucket - Ready Strip - green goo cuts through several layers of paint.

None of the four of my small block shrouds have a dash in the part number string. I don't have a re-pop on hand, so I can't determine if that is the case, or maybe a later production original GM. Anyone else have an example ?

Been doing gm parts for 27 years never have seen a dash but nothing is impossible with parts sold hundreds camaro fan shrouds. That said take that part number to your local dealer last checked was still available from gm but was on disco list. It would best if you don't tell them what is for because some people do not like looking up parts for old cars.

Here's a picture of the part number on the shroud - sorry about cr@ppy cellphone image, but you can see the dash between 4th and 5th digits.
Maybe that is a way around the GM copyright issue for reproduction parts, use the same number but add a dash?
I should probably explain, I live in Australia so not very easy to get parts, there's no local GM dealer (unless you want a Holden....).

Where are you located? It is a Home Depot staple, but I'm sure you can order a bucket on-line. It is cheap, non toxic, and I have used it on 60 year old fiberglass with up to 7 layers of oil, lead, and acrilic based paint sandwiches and never had a failure yet. Takes some time and leaving the part in the sun to heat it up helps alot, as well as a low power setting power-washer.

a chemical that doesn't harm fiberglass or fiberglass bonding agent, might not be so harmless on a plastic or rubber part...  i'd be careful and do a test area before using it wholesale on non 'fiberglass, metal, or wood' materials.

LOL yeah I guess not. Well like I said it is organic and safe on all materials except paper.  I think it is citrus based. You should be able to find the equivalent there I would think.
This link accepts Australian dollars so I would think they can ship it there? Worth a call or email.

Good suggestion, but I would try DOT 2, 3, 4 or 5.1. I'm not sure the Silicone DOT 5 will work.

Spoke to a model car guy says ATF will strip paint from plastic. Can't verify, would try a small hidden area first, but I bet you can get it.
