For years now we've used a no-sand primer as the tie-coat for painting non-skid
and there is no reason it wouldn't work just as well on an overhead.

It works excellently and we've never had a failure. Our primer of choice is
Pettit 6999 Bottom Prep. The Interlux version also works well.

The primer is very thin and will not fill the texture. While to some it might
seem overkill to use a 2 part LPU as the top coat it is actually a good choice.
LPU is also a thin paint and will not fill the texture like most 1 part
enamels (Brightside/Easypoxy etc.) will.

If you use the Pettit, the initial coat of top coat will tend to a grey color
but that will disappear with a second coat.

Joe,

Thanks so much for taking the time to reply to my inquiry on
rec.boatbuilding. Your reply certainly made the most sense When I
decided to use Awlgrip my thoughts were on its thinness preventing
texture filling as well as future cleaning since the Awlgrip surface I
hope to end up with should wipe down fairly easily.

Are you married to using Awlgrip ? If you aren't I'd suggest you look at using
Interlux "Perfection" instead... Lower cost; easier application; comparable
performance.

My question to
you is if the Pettit Bottom Prep 6999 and the Interlux equivalent will
actually work as a base primer for Awlgrip and, if so, how long will
I have to wait before appplying the Awlgrip?

A very short time... Depends on ambient temp but can be as soon as 2 hours.
Basically you overcoat before it really dries. Clear directions are on the can.

I am sure Awlgrip would
tell us to use only their generic primer but we know how they like to
sell their own products.


Certainly ! Like their "Alumiprep" is available (under another brand) at any
auto paint supply store for less than 50% of the cost.

While we are on the subject of primers I wonder if you have ever tried
CPES (clear penetrating epoxy sealer).

Yes, we've tried it but use the System Three "Clear Coat" in preference. The
clear coat has more solids and lasts a whole lot longer (we use it as prep under
varnish).

I wonder if it too could also be used as a primer for
Awlgrip.


Not unless you can sand it...
