One disadvantage of Imron and other polyurethane paints is they have
hardener. So there is no way to have a paint shop put the paint in a
small aerosol can and use it periodically to paint your chips,
scratches etc. If you did this, it would harden.

You can have acrylic enamel mixed to match and use it for touchup. Aerosol
for touchup is not the way to go. There are much better methods. Get a good
auto paint manual for instructions.
