If it is really teak, it's oily.

After a while, the varnish loses it's grip due to the internal oils in
the teak.

You can put a 100 coats on and still lose.

PLAN; A

Only thing I know that works, is to wipe down the teak with acetone,
then apply a coat of epoxy TOTALLY encapsulating the teak.

Allow to dry for 24 hours, then lightly sand and apply another coat of
epoxy.

Repeat daily unit you have 4-6 coats of epoxy, then allow to cure for
about 10 days, then lightly sand and start applying coats of varnish
that contains UV inhibitors on a one coat a day basis, sanding lightly
between coats.

About 6-8 coats should do it.

Keep a nail polish bottle full of varnish and a ScotchBrite pad handy
to repair scratches immediately.

Be totally paranoid about protecting tho table when ever anybody comes
around.

PLAN: B

Screw it, let it go silver and enjoy life.

Have fun.

SFWIW, building a boat with NO external teak or any other wood for
that matter.

Plan B for me... Tom
