I have no experience with TeaQua either - but, with such little teak on a P28, varnishing may not be that much work - considering you're just talking about handrails, toerails and hatchboards. There's no mistaking the difference a well-maintained
varnish job has over anything else on the market today.
However - as pretty as it looks . . . I hate the initial
8-10 coats traditional
varnish requires, the
bi-annual, between coat
sanding and
varnish recoating of exterior teak.
With all the exterior teak on my boat, after stripping, I chose to apply 3 coats of Cetol Light, with only
ONE annual maintenance coat of Cetol clear gloss . . . no sanding between coats, and with experience, no blue tape needed either. Looks great!
