After properly sanding the teak that cover my cockpit seats I going to apply
Cetol Light.
I do not know if I should tape the black caulking shown between the teak
planks, paint over it or trim each blanks individually to avoid
contaminating the caulking? If I paint over the black caulking will it
impair the looks and craftsmanship? International (Cetol) technician will
not endorse the responsibility if their product damage the integrity of the
caulking. This means that I will have to tape every caulking joints between
the teak planks or use my paint trimming skill!!! Any help will be
appreciated. TIA

I don' know whether cetol will cause deterioration to the caulking (I
doubt it) but it will stain or discolor anything it comes in contact
with. To properly apply Cetol have a brush in one hand and a solvent
soaked rag in the other. Any drips must be cleaned up immediately or
they become a permanent part of the boat thereafter.

It is likely that the caulking is a Sika product, at least here it is
the most common caulking used with teak. you might try contacting Sika
to see what they say about the effects of Cetol on the caulking.
