[Healeys] Seam sealing extent

[Oudesluys]

When the car is painted only little primer/paint will end up in (these 
lower) seams. Using the correct type of Waxoil, Tectyl or similar in the 
cavities will also protect most seams and if you apply some externaly on 
the seams you have 100% coverage. It has a high penetration in the seams 
and if applied properly (just a mist will do) will not crack. Make sure 
no water can be trapped in cavities by drilling 1/2" holes in the lowest 
points (front and rear) and remove the ex- and  internal burs. In most 
cars these holes are already present or there are raised parts in the 
welding flanges of the seam to create a channel. Insert a suitable bar 
in the hole and move the bar backwards to lower the front of the hole 
and raise the rear. This creates a slight vacuum on the move and will be 
the cause of some air circulation in the cavity.
Clear these holes or channels regularly to keap them open. Repeat the 
Waxoil treatment every 2 years or so.
