Please note that the PICTURE UPLOAD function is not working. The iBoats Forum Moderators are working with the system administration folks at the parent company to get the issue resolved. This happened about a year ago and here we are again. In the meantime you can post photos as links to a picture hosting site of your choice. We are sorry about the inconvenience and will advise when the issue is resolved. Thank you for your patience.
What is the best method for removing anti-fouling paint from my boat bottom? There appears to be several layers of build-up. Chem. strippers vs. sanding. What is the most agressive means of sanding I can use without damaging the gelcoat?
The best method to strip the paint is by using one of the gel strippers specifically made for the job. The gel is designed to stick to the hull, rather than dripping off like the liquid type will. After the gel is applied a mask is laid over the gel to keep it from drying out while it is working. When everything has softened up the paint is removed by scraping. A reapplication or light sanding may be required in stubborn areas.<br /><br />Try this link to some products available at boatfix: http://www.boatfix.com/catalog/722.pdf <br /><br />As to sanding it off and possibly damaging the gelcoat, the gelcoat would have been sanded with 80 - 100 grit paper, scratching it for a mechanical bond before the bottom was painted.
