Fomaspeed Variant 311 is the RC glossy paper in the Foma range. Rich neutral blacks, the paper can be quickly processed through standard developers & fixers. Given a rapid wash it will then dry flat to a high gloss. If you don’t have access to a heated dryer it will dry just as well ‘pegged out’ on lines.
Glossy RC paper has a very high maximum black (Dmax) although this is outweighed to some extent by the reflections due to the high gloss finish.
