In the last communication I had with Poly Fiber some time ago, their =
tech
advisor was adamant that the Smooth Prime be covered with an epoxy =
primer to
seal it, and then move on to primer for the finish coat, then finish =
coat.
The UV Smooth Prime does not require Silver Shield because it has enough =
UV
blocker in it to do the job.   So my understanding of the sequence is:=20

1) Superfil for final shaping
2) Smooth prime to fill pin holes, sand smooth. =20
3) Epoxy primer to seal the Smooth Prime and prep for finish
4) Finish coat, or finish primer and finish coat. =20

Always make sure the finish coat and its primer are compatible.=20

It appears that the problem may arise from the failure to seal the =
Smooth
Prime with epoxy primer.   But look to the manufacturer for the final =
word,
since I am not a finish expert by any stretch.

Gentlemen....

  My Lancair 0-235, which were scheduled to fly this spring, has got
blisters!
See photo.
 =20
  The aircraft was painted according to instructions made by Poly Fiber, =
Jon
Goldenbaum as follows:
 =20
  1) SuperFil to cover pin holes in the structure.
  2) Smooth Prime
  3) Silver Shield
  4) Smooth Prime
  5) Aero-Thane
 =20
  The aircraft has been hangared in an unheated hangar for the last two
years.
  The bubbles were not there one months ago.!
  Humidity has been high the last 2 months, but I never expected this to =
be
a
problem.
  By puncturing some bubbles water seems to appear.
 =20
  Have any of you encountered similar problems?
 =20
  Best regards
