What Is The Right Thing To Do? (Bottom Of The Car)

[Werup]

Hi,

 

This forum has so much experience, and I am in a situation where I am not sure what is the best/right thing to do.

 

I restoring an early 1971 240z, and I just removed the rest of the suspension and the fuel tank from the car, so now it is completely stripped down. The car have had a very nice PO which did take car of the care and got it tectyl protected when it was in the states. So I have found very little rust on the car

 

 

The tectyl in the arches are so stiff that it is cracking of when im using fiber scraper, so im going to remove all of that before the car goes to the painter - but the tectyl underneeth the car seems to have very good connection with the paint! Of course it is dirty from being driven. but other then that, it is good.

 

 

 

I am going to paint the car in black when finished, so i doing a color change - that got me thinking:

 

1. Would it be better to get the bottom of the car sand blasted and the metalised with zinc (not sure it spelled like that) and then painted it and resealed. 
    
2. Not remove all of that good tectyl and just clean the surface of the bottom. The tectyl is applied in a thin layer, and is quite hard, so it does not hide rust pockets. 
    
3. Try to remove all the tectyl with a metal scraper, down the the paint - this will be a not so funny job and a long one... But maybe a good way to keep the old paint and not removeing any tectyl or paint places, where the painter will struggle to repaint as as the factory.

 

I am asking because im not a fan of removing the good stuff and then afterwords find out that I gave rust a free pass to ride with the car   

 

Hoping to get some experienced opinions, so I am getting to know the pros and cons.

 

Thanks, Martin

Do whatever will let you sleep the best at night.  I used a heat gun and scraper to remove my undercoating.

Also you better put that large rear fuel line insulator with your other unless you plan on buying a whole new set from me.
