I have been working on my 15' v-hull for awhile in terms of paint. I used Benjamin Moore industrial paint on a few areas inside the boat, it looked great. A couple days later I went back out and it had wrinkled all over the place. I sanded down what I had painted to start over. <br /><br />I went and got some Pettit EasyPoxy primer (undercote) and preped the surface by lightly sanding it and then I mixed amonia and water together as Pettit tells you to, and cleaned the surface. <br /><br />It also wrinkled the next day. I sanded down the wrinkles and applied another cote, which was slightly better but not by much- it too is wrinkling in a lot of areas. In these areas I can take my fingernail and remote the paint down to the previous surface. <br /><br />I am doing very light coats, my temp is about 50-55 degrees in the garage. <br /><br />Please let me know what I am doing wrong, thanks a lot. <br /><br />By the way some of this paint isnt over bare epoxy it is over a year old paint job and there doesnt seem to be any reason as to which surface has the problem, they both are equally problematic. <br /><br />Thank you. <br />-John
