It's Been nearly a year since I applied flex seal to the complete seal around an old bass hunter boat,I also coated the inside areas that were showing some spiderweb cracks .Im pleasantly pleased the flex seal has held up very well,I left it unpainted so I could inspect it better.
I also left the boat exposed outside,again it has held up very well.I will paint it and call it a success,I use this little barge to skirt small creeks to set my trotlines and bank lines for catfish,so far it's sustained the rigors of it well.
