Re: [papercreters] just wondering




In the aircraft industry the protection of parts is crucial especially where one can not get to the parts to repair, or correct deficiencies.  One of the the things that smaller fabric planes have is a fuselage made of chromemoly tubing.  This tubing rusts fast (overnight) so a viable means of protecting it from the elements is crucial.  One method of protection is primer.  It is generally sprayed on in leght multiple layers.  However, the best method is an epoxy primer (also sprayed on but much more durable).  Epoxy primer is two part and very unhealthy for humans (in the un-protected state).   Good airflow and complete mask assembly is needed if painting in an enclosed area, while if done outside just a mask (respirator) would be sufficient.

If you sprayed this on your chicken wire you would waste a lot of it to overspray, but with an HVLP (high volume low pressure) spray outfit you would lose less.  Chicken wire completely encapsulated with epoxy primer would be stable forever.
