How to clean frame on true Survivor

[David D.]

I could have swore that i have previously seen information/pdf explaining the appropriate way to clean up a true 'Survivor' car frame and underside, without removing the essential 'other' markings that are on the frame from the factory, but can't find.

Friend has a '67 BB roadster with 30K original miles..... that he wants to clean up and remove all the dealer installed under coating and years of road grime, but is afraid of how to proceed without also accidently taking all 'essential' markings off in the process.

1. Anyone have or know what is best way to proceed?
2. Is there any pdf or articles that describe how to take on this challenge?
3. Is there documentation that tells one the approximate locations for these factory markings?

Thanks,
David

That's a tough one, David. Since the dealer undercoat and the original frame "chassis black" are composed of basically the same thing, anything that would remove one would also remove the other.
Both are a tar base coating and any type of solvent, such as mineral spirits, or probably any petroleum based cleaner, will disolve both coatings.

Michael,
Thanks for the reply. Is there documentation of any type that refers to the 'typical' area as to where the factory might have placed markings?
In orther words, the way I'm thinking is that we could/should probably be able to remove about 80% without ever affecting under lying markings, IF we knew where they might be located on average. I would think that each area of importance, had their own 'general' areas as to where they would have scribed frame markings......no?
Thanks again,
David

That's probably a good idea. Hopefully, someone that has pictures of the various locations for shim marks and other markings/numbers will post some pictures.

When I cleaned the underside of my car, I was told that the undercoating in the rear wheel wells was factory applied. Also, the very underneath of the fiberglass where the seats are located should be natural fiberglass I believe.

That's correct, Chris. The wheel wells (front and rear) receiced a splash of undercoat at the assembly plant.

Most of the under side of the floor pan should be natural, unpainted without undercoat.
