REFLECTOR: Smooth Prime

[Scott Derrick]

A couple years ago I had to remove all the top coat and smooth prime 
from my canard.   It bubbled when exposed to rain.  I used Polyfiber's 
primer and top coat system and had the problem.  Somebody suggested it 
was the propane heaters I used to heat my shop while painting that 
caused the poor adhesion, 

I don't know what caused it but I won't use it anymore.
