I haven't any experience of the kbs coatings,but if you type into the search section of the forum,you will find many,many discussions on the subject of POR-15.

I personally have used POR products throughout my 'build' and have been more than happy with the results!

One thing to bear in mind though, POR-15 is U.V. sensitive.
Not so much a problem here in Scotland,but in sunny Ca.??? grin
It can be overcoated with their Chassis paint though.

Happy searching.
