Glaco Compound Roll On is a Japanese-made glass polish in a roll-on bottle with an integrated felt head, made to strip traffic film, water spots, mineral deposits and old coatings before you apply a rain repellent. Its dual-abrasive formula pairs fine hard abrasives with larger soft ones, so it cleans and prepares glass in one pass without a separate applicator. It suits drivers who already use a glass sealant and want it to bond and last, and anyone restoring neglected or coated windshields. Against spray-and-cloth glass polishes, the built-in head is the main difference; it is a preparation step, not a stand-alone rain repellent.

Rated 4.8 out of 5 from 157 ratings, buyers largely report that it cleans glass well and leaves a good base for a glass coating. Complaints are few and mostly about the small bottle and needing extra passes on stubborn film.
SOFT99 Glaco Compound Roll On is a glass polish and preparation compound for exterior automotive glass. It removes traffic film, water spots, oily contamination, road grime, mineral deposits, and remnants of old windshield coatings. It is used to prepare glass before applying a glass sealant or rain repellent such as SOFT99 Glaco Ultra.
The Japanese-made formula combines fine hard abrasives with larger soft abrasives. A felt polishing head is built into the bottle, so no separate applicator pad or sponge is needed. Shake the bottle, apply, polish, and rinse. It can be used on the windshield, side windows, and rear glass.
It also removes old Glaco coatings before a fresh layer is applied. It does not remove glass scratches. Apply it out of direct sunlight, not on hot glass, and use light pressure. Do not let the compound dry completely on the surface.
