have a 27 foot walk around recently bought not knowing much about fiberglass boats i had no concern about many cracks above the rub rail on gunwale i believe after doing some reading im becoming a little concerned now about structure safety because there are alot of gator cracks the sides below rub rail look like new it is 14 yrs old is this a common thing it looks like it bounced off of some tie down poles throughout its life cause rub rail track is broke in spots but not where the cracks seem to be bought from a dealer with some other issues being resolved by them should i make a stink about this or isnt it much to worry about raced cars for years so was gonna feather back edges glaze it and was actually gonna use white roll on bed liner and cover it up herculiner makes white and i thought id blend it from the top of rub rail to the bend stopping short from the top since there are no cracks there
