Good Luck with that
I've had my own shrink wrap equipment for six years. There is opportunity to make money but many reasons to avoid this businesss..You can't do it when it's windy (and it usually is in the fall).You can't do it when it's raining..Most marinas in my area do shrink wrap and won't appreciate a third party taking their business away. They require a certificate of insurance to work at their facility. What happens if you damage someone's fiberglass, gelcoat, stripes, sails or canvas? What happens if you manage to put the heat gun near the fuel vant and create a fire which affects the entire marina?.The frame materials is expensive for big boats..In my yard the boats are stored inches apart and it's almost impossible to get the equipment between the boats aor reach high up on larger vessels..Many yards charge an hourly fee to have vendors work at their facility.Many folks are not dependable to have their vessels hauled and ready when they say they will be. I do a few friends each year for free and scheduling is a problem more times than not..Fuel and propane prices won't help your profit..The boatyards are able to keep busy hauling boats, pressure washing and winterizing. They wait for the proper conditions and wrap boats between other jobs..When a customer opens his vessel in spring time and it has mold and mildew due to inadequate ventilation are you responsible?.When blisters appear on gelcoat or painted surfaces under the wrap are you responsible to fix them? Ever wrapped a painted vessel?.Purchasing and shipping the plastic costs a lot if you don't have a wholesale supplier. Wholesale you can buy a 20' wide role for about a buck a foot which is 25% of the West Marine price..If it was that easy more people would be doing it. Insurance, transportation labor and supplies may take a substantial cut out of your profit potential
