no the cavalier is not a flat top , these cans are all pretty much from the early 70's era . the grand prix is the dominion store brand cans . I think the cavalier ginger ale would clean up more , but don't really have the right stuff to do that myself .Some nice cans there! Is the Cavelier a flat top? I like the design on those Grand Prix cans, very 1960s. Are those the Dominion brand ones? Never seen them before. Looks like most of these would clean up pretty well with oxalic acid.
was planning to go back and look for more but we have some snow today so have to wait till it clears up
