[Rhodes22-list] Bill Davidge ... before painting...

[Robert Skinner]

Bill,

Three things to take into consideration:

* Not all acids have a smell.

* Many blisters are acidic.

* It can't hurt to treat any blisters as 
evidence of FRP breakdown.

Ed's advice to make sure that they are all 
ground out is valid.  It doesn't take long 
to clean them up, and once done properly, 
filled, and followed up with a good quality 
epoxy paint, they often do not recur.
