These paints are cured with isocyanate (containing cyanide) compounds and
are QUITE toxic . If brushed or rolled, only the solvents become airborne
but if sprayed, a fraction of the paint is atomized into the air. This is
very toxic stuff and should only be sprayed if you use supplied-air
respirators.
A good job can be done in applying this stuff by roller. but it isn't easy.
Most importantly, plan to do the whole side in one go and have all your
equipment and materials together. Best to have two or three people- one to
roll, one to tip off the rolled material with a foam brush and a third to
fine-tune the thinning of the paint, pass the painters a new brush or a
clean rag, answer the phone. etc. The Interlux manual is good.
If the boat won't be subject to abuse, these paints are worth the effort.
They will stand the weather for many years.

Most especially if the sun is shining directly on the surface to be
painted, don't paint.

If it is evening, and the bugs are coming out, don't paint.

Unless you have an environmentally secure and controlled space, pay
special attention to the above three items.

Yep.

Do not leave off painting before the job is complete (a ridge will
result that is impossible to cover up without sanding)

Applies tom almost any paint, especially LPU.


Do not have more than one wet edge to your paint job at any one time
for same reason as above.

Yep

Do recoat within the allowed time window to avoid re-sanding.

Yep

we sell LPU paints and I've recently played with them on a 12 ft firefly
sailboat I am restoring. I have tried all the different methods, roll
and tip, expensive brushes, etc. and have pretty much concluded that one
should really spray these paints (I have yet to try spraying!). Yes,
brush/roll application seems to be an art form.

comments anyone?

IMHO, a JGA gun with a 2 qt remote pot which is about $400-$500 for the
package is the only way to go.

BTW, you'll need a compressor that can deliver at least 15 SCFM.

A 5HP, 2 stage compressor with an 80 gal receivor barely does it.
