i just made a deal on a old 14 ft richline alum. boat. some past owner caulked with latex or silicone caulking it's smeared all over every thing. seams, rivets you name it. looks god awful it can't leak that bad if it did. so whats the easy way to remove it? i know it don't take long for gas to mess it all up how about carb cleaner ? the inside looks like it's been painted a time or two flaking off. was going to use a angle grinder with a wire brush on it for the paint inside. any ideas about all the sealer removal ? some one have a clue what it would cost to have a small trailer sand blasted???
