With the cabin side rails being of Oriko, a very oily wood, painting seems to be an annual task. After taking advice from Jim off Chertsey this could be the last time for a while, fingers crossed!
Jim recommended washing down with an Acetone base fluid immediately before applying a Sikkens special primer.
After hours of rubbing down then cleaning with acetone base panel wipe I applied a coat of the primer. It's like painting on glue, but you could see it soaking into the grain, unlike the other stuff that just sat there then peeled off.
