Primer as recommended by manufacturer. Topcoat: Coating to match
adjacent surfaces. Surface preparation and number of coats in
accordance with manufacturer's instructions.
NOTE: Apply sufficient coats of MPI 113 to achieve a minimum dry film
thickness of 16 mils 400 microns.]

(Substrate C). Use MPI 72 in severe environments
for a durable, glossy appearance. Use latex systems
where MPI 20, MPI 101, or MPI 108 is not allowed.
MPI 72, urethane is allowed in California. For
selection of top coats, use the first bracket option
for geographic areas that do not have harsh
environmental conditions. Use the second bracket
option for areas that have harsh corrosive
environments.
(Substrates F and G). For overcoating existing
alkyd, latex or epoxy systems refer to Evaluation
Section of MPI Repaint Manual.
(Substrate F). In the first bracket option, select
appropriate top coat. Use first top coat option
for geographic areas that do not have harsh
environmental conditions. Use the second top coat
option for areas that have harsh, corrosive
environments.

(Substrate K, L, and M). Heat Resistant Paints may
require a high heat cure cycle to achieve proper
cure. Curing requirements should be determined
before specifying so that the supplier will be aware
of requirements.
(Substrate K and L). Consider hot dip galvanizing,
aluminum metallizing, and zinc metallizing
alternatives to the specified coating systems.
(Substrate M). Consider aluminum metallizing
alternative to the specified coating system.
