You have a Davidson’s shop in Pretoria west that sells fiberglass resins and glass sheeting and other . I bought from them a coarse polish paste to remove oxidized gel coat . It worked the best . Then I firstly bought a orbital polisher from Adendorff - it’s large blue one with speed regulation . Was on R 890 . It’s an excellent tool but you must watch not to burn the gelcoat ! Then in later stage I bought a Rupes big foot professional random orbital polisher . That machine makes a job done in no time on Seacat 565 but it costs a lot .
Polish - I tested few and I found a very good if not the best at Ravenol in Cape Town . It’s called Auto Glym Super Resin Polish and Auto Glym extra gloss protection. It’s worth the money as it’s protects for very long time . Once a year , you will be good .
