       Greg, I have used POR-15 extensively, in fact I just got done 
POR-15ing all the rust susceptible metal parts of two 1.9 engines yesterday, 
and you do not need to use the tie-coat primer IF you apply the primer or 
whatever next coat before the POR-15 has completely cured.  Once the POR-15 
has cured you must use either the tie-coat or lightly scuff the surface with 
fine sandpaper or a 3M cloth.  If your using the POR-15 on the engine tin you 
do not need to top coat the POR-15.  It is protection enough.  POR-15 only 
needs to be top coated if it is exposed to ulta-violet light, sunlight, which 
only affects the shiny appearance not its protective qualities.
