I have a Swift caravan which is still under warranty. In preparation of the van to go on holiday I noticed the appearance of yellow patches on the rear panel. Has anybody else come across this issue?
Just a thought, have you washed the caravan with Fenwicks Caravan Cleaner? This is yellow in colour and if not rinsed off thoroughly can cause damage of some sort. Fenwicks warn not to allow it to dry on bodywork.
