Is it a grout, a filler, an adhesive or what?

[NC Mike]

It's been a while since I posted,and I apologize, but work's been busy and the LBC's occupied a good portion of my "free" time.

It's body work time. The 74.5 MGB-GT looks really strange without doors or a hatch or any trim and I'm warming up the sander.

I've taken notice of a material that is present at all body seams.

It is rigid, white, and was used to fill/fillet transitions from one panel to the next. In all instances the material appears to have been in place and painted with the car when it was new.

In many places, this material is falling off as I sand or prepare for sanding.

In most places it is "finished" about the same way you might "finish" a bead of caulk around a plumbing fixture or a window glazing.

I'm undecided , obviously, about what it is, but more importantly, I need to know what to use to replace it.


Thanks,

Seam filler I'd bet. A shop with restoration/body-shop supplies should have a modern version of it.

It's seam filler. It was applied by the factory. You can buy it at most auto parts or autobody stores.

Hi Mike,

The stuff you are talking about is called seam sealer. Like the name implies it is applied beefore painting and priming to seal the seams against moisture. I can't tell you what it is made of but the stuff is tuff and seams to work really well. 3M makes a brand of it and Eastwood also carries it. It runs about $20 a quart according to Eastwood's latest catalog. Probably available and cheaper at the local auto parts store.

It can also be purchased in caulking gun tubes at about $20. per for easy application. It's actually the consistancy of regular caulk, a little more runny and sticky. You can but it at O'Riellys. /ubbthreads/images/graemlins/hammer.gif
