I have these blisters and would love to read Studebaker Service letter W-1963-1.

Can somebody send me a picture of this letter please?

Hi Kodjo….. I no longer have that letter, however, it’s point was… Water absorbed into the fiberglass from water sanding operations will eventually expand under the new paint when continually subjected to warm temperatures (sun).

The factory suggested the repairer do his utmost to make sure the (fiberglass) is completely dry.

Years ago I stripped a '63 Avanti with paint remover down to bare fiberglass.  I then parked it outside in the rain and hot sun for more than a month.  I had already washed the body with a lot of lacquer thinner.  As I recall my procedure was based on the advice of experts.

I then sprayed the primer and did the bondo work on the seams.  A body shop sprayed the urethane.

To this day the paint is perfect.  It has been garaged, however.

Another Avanti locally that was stripped down to bare fiberglass (by someone else) has not fared so well. It has sat in the sun and quite a bit of its paint has bubbled or pealed off.

Posting this on both Forums. While this deals with acrylic lacquer, I assume it could affect other paints as well.
