GPL 205 grade 0 (205g0) is a high performance grease that is used extensively to lubricate mechanical keyboard switches and stabilizers. 205g0 is recommended for linear switches and Topre. This lubricant has been utilized extensively due to it's ability to transform scratchy stock switches into incredibly smooth switches.
If you wanted to use this lubricant on tactile and wanted to keep the bump, care should be taken to avoid the tactile legs of the stem when lubing.
