Been going over the paintwork with Meguiars 105 compound and having good success with the swirly cobwebs but I've run out now and cant find the medium sized bottles anywhere,ordered poorboys compounds 3,1 and liquid carnuba from net but found using the 3 was like grinding paste and undid all my good work on the tailgate. Was wondering what to use,have seen ultimate compound but was not knowing how this compared to 105 in strength or abrasion.
