Don't use fibreglass cloth that you buy at Walmart.That is a 6oz. cloth and is way too heavy for float use.Use a 1 1/2 to 2 oz. cloth to glass the entire float top and bottom.Some will use a 3/4oz. cloth on the upper portion but I personally don't like using cloth this light for float use as it is just too easily damaged from shore and floating water debris.For ease of use and smell tolerance,I use Z-Poxy finishing resin and it is very easy to work with because of its long pot life.Gives you plenty of time to position everything and get any bubbles or wrinkles out from under the cloth etc.By glassing the entire float you are not only strengthening the structure as a whole but also sealing the wood from any chance of water penetration.You will find that your paint will also adhere better and your floats will also last a lot longer.It's a lot of extra work but the finished product can not be compared to a plastic film job or just painted wood.It's way better than that if you take the pains to do it right.Mine are almost 10 years old and they just keep on trucking,and I DON'T baby them when I'm flying with em either.They show absolutely no signs of water penetration or paint adhesion problems.Be careful though,just because its glassed doesn't mean its bullet proof.It can still be easily dinged and dented if your not careful with them.It just takes a liitle more carelessness to get them that way
