I have my 07 PII in for some minor scratch repairs on the boot and the place that is doing the work for me are some friends of mine that have a body shop and do boat repairs also. They wanted me to leave the boat hanging off the trailer as much as possible so they could get to one of the spots they were going to work better so I did. I dropped it off at lunch today and they looked under the boat to see how much easier it was going to be and immediately said “you have blisters in your gel”, and I laid down to see what they were looking at and it is blistered where it sits on the bunks of the trailer. What might cause this to happen? I fish year round and fish in temps from the teens in the winter to high 90s in the summer. I average at least one trip to the lake a week year round also. I did not know if it might be something to do with me loading it and hauling it in some extreme temperature with the bunks wet or something else maybe. The boat is kept in a garage in my basement everyday also. Forgot to mention they are not going to repair the blisters because they have no way of lifting the boat off the trailer. All of the repair work they do on boats is on the cap or sides of the boat 98% of the time. I talked them into working on the bottom of mine. Thanks for any info, TravisLast edited by TnSabre on February 9th, 2009, 5:49 pm, edited 1 time in total.
