All the aforementioned sealants will attract dirt - this I know from personal experience. The best method is to use one the aforementioned sealants but keep the sealant gap to an absolute minimum.
Good Luck.
Being unaware of the exact problem makes it hard to recommend anything but if its only to seal rather than hold maybe some butyl mastic will do the job.
