Best cab repair option??

[DYNAMiTE]

First off the truck wont be a show truck but more of a street rod..... The floor pan has rust holes about half dollar size on both sides and the rockers are rusted through about a quater size in spots on both sides.... The cab corners arent rusted but one has been dented and repaired before. I was wondering if any of you have opinions of repai kits where I can buy it all together for a good price. I ws also told about POR-15 repair kits with resin tape or something. Any ideas about this? I have done a little research on this stuff but I work 15 hour days and dont get much time to look it all up. I will post some pics of the truck ASAP and thanks for the input in advance!!
