Tons of turpentine with a towel (soaked) over the top them plastic sheet to stop evap. Wait half a day and it will fall off. Plastic scraper assists.
Wash well with tons hot soapy water.
Wet sand the bottom and rails with about 1200 or 1500 and it will come up beautiful
Regrip self explanatory with whatever EVA you like.. Looks like no dings so that will bring it up like new.
