Had prefab granite vanity top installed. Granite sealer by "Tile Lab" was applied with sponge and 2 hours latter 2nd coat added. When it dried all streaky and dull I realized it should have been wiped off but never was. If I add more sealer will it react with previous and wipe off shiny (I would need tech to come back with more sealer)? Do I need to use Tile Lab stripper/cleaner and start over? Any other options?

Thanks
