Have not tried this but sounds good!
Quote from Andy Clarks web sit.
"By far the best RIB and boat cleaner I've found. Despite owners using expensive proprietary cleaners from the boat business, our customers can't believe the difference when using Micro-TFR for the first time. With little effort, you will restore your boat's original colour. Can be diluted with 5 parts of water, but if used neat in an atomiser and spread around quickly with a sponge, the affect is dramatic.
Normally used by the trucking industry for cleaning curtainsiders, this cleaner works well with jetwashers. Wear rubber gloves if using neat."
