Re: Exploding Shellac?

Charlie,

Having had to do this several times - I found out what was causing it on
mine at least. Obviously the high temp of the two dissimilar materials -
glass and metal but the main reason was that the mirror base was not flat
and even had a small, sharp bump in the casting. I did the Scary Harp
routine on it, cleaned the glass and base with alcohol then applied some
standard CA (super glue) and that mirror hasn't budged. The car is in Fla
now with my mother-in-law and its still attached. So look at the base
closely.
