Evan, what was the oil?  Any damage to the FG might be in the future of the

yak as the oil penetrates the lay-up.



Dave - It was "Daly's SeaFin Teak Oil".  I looked on the label for the
ingredients, but it only said it "contains petroleum distillates".  I did
this about 6 months ago and haven't noticed anything yet.  I just applied it
with a rag, wiping it off after a few minutes.  I'm getting the feeling
maybe this wasn't such a good idea...

Evan, here is a site which lists the manufacturer's address (click on the 
MSDS).  A phone call might allay your fears: 
http://www.dalyspaint.com/catalog_seafin.html

One expert on wood finishes lists the ingredients as:  "Daly's SeaFin Teak 
Oil. This is a blend of tung oil, with alkyd and urethane resins that 
produces a soft satin lustre. Contains mineral spirits. VOC = 550 g/l. 
Volatiles = 70%. Liquid colour, slight amber. "  (from: 
http://www.arbortech.com.au/articles/017.html )

Based on this composition, I suspect the stuff is relatively harmless to 
cured fiberglass resins.  Over half of it is volatile mineral spirits (e.g., 
paint thinner), with the rest tung oil and [basically] varnish-type resins. 
The resins won't hurt FG.  The mineral spirits will evaporate.  Tung oil is a 
"drying oil" widely used to finish boat decks and fine woodworking, often 
next to fiberglass.  A good synopsis of its properties: 
http://www.realmilkpaint.com/oil.html

Probably the only down side would come if you decide to repair the hull after 
a puncture -- the coating you applied would have to be removed by sanding. 
Thank heavens it does not have any silicones in it ... they are a b**** 
(rhymes with "witch") to remove preparatory to adhering more fibeglass resin 
to an old hull.

One of very possible consequencies - you'll have to rub it out with some
solvent before painting or applying a jel coat. Even then some of this oil
might remain in scratches.
