Anti corrosion strips - Worth it?

I am about to reassemble my fenders and I see on Moss that they offer an anti corrosion strip for about $75.00. I am pretty sure it is some type of stock rubber weather stripping so it is a lot of money for a strip of rubber.

Has anyone ever installed this strip...is it worth doing? We I dismantled my car I didn't see anything like it on the car...but maybe that is because it is a restoration item.

Thanks in advance.

What corrosion did you find in that area when you dismantled your car?
What did you do about it?

In MY opinion, gavalnic corrosion between the dissimilar aluminum shrouds and the steel fenders probably won't be a problem in your lifetime.

I'd thoroughly prime and paint both faces and bolt them together. If you want to stop galvanic through the bolt, put a rubber washer under the head and the nut to isolate them from the panels.

The last thing that I'd do is to pay $75 for a roll of electrical tape.

If you do insulate the fenders from the shroud, pay attention to where/how you ground your lights.

I agree as it is difficult enough to get the stainless bead installed without the addition of a sticky strip of rubber. I don't think they were originally painted near as well as our restored cars. Have a good day!

That strip is not a rubber strip. Some call it dum dum. It's sort of like sticky silly putty, that a comes in a roll or in strips. It will flatten out when pressure is applied. I believe 3M make a similar product. This product is black in color.
 
:iagree:

With John and Tim. Save your money. Further, since the steel fastener interfaces [Bolts] can not be eliminated and they have relatively small areas the corrosion at these locations can be very sever compared to what would occur at the larger mated flange areas.--Fwiw-Keoke
 
I have read somewhere there are one chemical product
(like a special grease or silicone ) that avoid the electrolytically corrosion from aluminum surface and iron -It can be also one yachting or aerospace product that have same problems
I remember the name DURALAC DTD 369B jointing compound

Just for my edification, do you know if that material supposed to act as an insulator, separating the two dissimilar metals, or is it a neutralizer to chemically reduce or eliminate the resulting effects of the corrosion?

If it is the soft, sticky, "Dum-Dum" that we all know and love for sealing windows and the like, I would think that when used in a metal-to-metal under compression situation, the high points on one or the other of the panels would eventually punch through.
