RE: First floats
You can put a lite 3/4 oz cloth on the top of your float and a heaver 2 oz cloth on the bottom ..You can use film like ulta coat but you dont save that much weight and peeling can be a problem...I prefer to glass them..They are much stronger and more leak resistant...You will need to paint them too but you can rattle can some stuff from the body shop supply store that is fuel proof..I biggest reason to put heavier cloth on the bottom is because of the impact of the water and scratching of the ground...The film will get scratches and holes in it , you almost half to glass the bottom no matter what...
