I could not find out what if any surface pre treatment is required on the
metal parts before you apply this paint, only the cure process. I wonder
where it is used on re-entry vehicles having worked for years studying fire

Bob,
Hope your life insurance is paid up. That stink can't be good for you to
breathe.
Never knew anyone to paint the inside of a pipe. Isn't there an A4 website that
discussed this issue?
I like Dwight's idea to use stainless steel. McMaster-Carr has fittings of
every type in 304 or 316.

OK. I know I'm cheap and use a lot of less expensive alternatives to popular
gear. For example, all the hardware on both my boats, except stuff I've not
gotten around to replacing yet, is Garhauer not Harken. My anchor windlass
is Anchorlift (from Scandanavia) instead of Lewmar
I really do appreciate the sense of adventure and discovery in trying out new
things for the boat.
But sometimes the tried and true alternatives are still a good choice.
A few years ago, a buddy and I helped an old guy at my club recondition and

I'm but an accountant not an engineer. Help me understand this stuff..
So if I use a 1990 34+ as the baseline, the hull was a composite of vinyl
resin, presumably glass matt and chopped strand, balsa core and Kevlar.

The schedule for the 1990 37+
Below the waterline the layup was one layer 1 oz. chop, one layer 1 oz. mat
and one layer of C77K/200 Kevlar Fabmat (a blend of fibreglass and kevlar
49) outside the balsa and one layer of C72K/100 Kevlar Fabmat inside. This
Fabmat is much heavier than the 1 oz.
Oops, make that 1.5 oz where ever I said 1 oz.
I think the changes in materials over the years makes less of a difference
that what Graham said, From hand layup, to vacuum bagging, to resin

these techniques results in a hull that is

So vacuum bagging essentially draws the resin into the substrate as opposed to
just letting it sink in? I could see how that would be more precise and
require less resin. On that note, resin adds minimal strength but bonds ?
All questions.

yes, clearly balsa would rot when wet where as the core cell would not.
Presumably the latter would just delaminate much like a blister? Is the
advantage of the foam core that any moisture intrusion would be more localized?
Is there a weight and/or cost benefit? I would guess the balsa
As I understand it, yes. The resin has strength but yields more that the
reinforcement. When a load is applied to a composite, the resin stretches
enough (while the reinforcement stretched less for the same load) to shift
all the load onto the glass or carbon or kevlar. The resin just holds it
Vacuum bagging clamps everything and draws out air bubbles, gives a more
consistent result with less resin. Resin infusion is vacuum bagging on
steroids, you pull a vacuum and you inject resin at pre-set points, the
resin is drawn in with great control - so even less material, better
results.
Got it - thanks

Most of the tension and compression strength in a hull thickness is at the
inner and outer edges. The balsa/foam/core cell? (that's not the right word,
but my brain is full at the moment) is a lightweight centre to keep the outside
and inside strength members apart. (like the web of a H beam
