[Rhodes22-list] Penetrol

Brad,

I got tired of paying huge prices for deck stain
that just wore/flaked off in a few months.  After
some research in "Wooden Boat" and other sources,
I decided to use boiled linseed oil.

Straight linseed took too long to polymerize, so
I added japan dryer.

With the dryer, the linseed did not penetrate as
far as I wanted to get protection through a Maine
winter.

Based on comments on this list and others, I
added Penetrol to the mix to help the linseed get
into the wood.  Bingo!

I now use the following mix for decks and stairs
- both cedar and old-style arsenic-treated PT:

87% Boiled linseed oil
10% Penetrol
3%  Japan dryer (adjust for temperature)

Brush on, rub in with a rag (use gloves).  Stop
playing with it when it starts to drag.

Penetrol also works on the 20 year old gel coat
on my little Potter 15 day sailer.  Pressure clean,
dry, wipe on Penetrol with a rag, let it stand for
a while (depending on temperature) and wipe it off
before it stiffens.

I'm a believer in Penetrol, but am pretty cautious
about what kind of surfaces I use it on -- testing
every one.  I suggest that you test it before
going whole hog on your gel coat.  YMMV.
