| Subject: | Proseal shrinkage ? |
--> RV8-List message posted by: "Paul" <paul@wilsonnet.flyer.co.uk>
After what seems many long hours of meticulously preparing the fuel tank parts
for final assembly, I finally got round to sealing and riveting the tank stiffeners
into both tanks late last week.
Everything seemed to go to plan, however, now after three days, I have returned
to start preparing for riveting and sealing the ribs in, I have noticed that
on quite a lot of the blobs of sealer which I put on each rivet on the stiffeners,
there appears to be a gap or hole appeared in the sealer, where I can see
through to either the rivet or side of the dimple , depending on where they
have appeared, almost as if the sealer has shrunk away as it has started to cure,
or if there were a small amout of air in the sealer which has now found it's
way to the surface.
I'm only talking of a pin head size hole here, but wondered if it was anything
to worry about, and is it ok to go over each rivet again with fresh sealer when
I do the ribs ?
There was no contamination on the stiffeners or rivets, as all parts were cleaned
and washed in acetone and dried prior to bonding.The sealer is fresh from Vans
last week.
All comments welcome.
