Thank God for the search capability on here and thanks @cruza driver for your comment.... @bigcol and I have what looks like gum sap stains from the weekends trip to Toodyay and "Elbow Grease and Fibreglass Cleaner" only removed minimal stain.The white bottle only use in a small area at a time and a bit harsher but good for removing gumleaf stains and the odd bit of bitumen. But it is a lot harsher I found on the fibreglass just dont rub right in with plenty of elbow grease beceause as mentioned on the bottle its a cleaner too.
gunna have to have a search now........
If you can't find the black one and it works on ours let me know..... I'll bring it over and sit back and watch you do yours
That "Rounduit" symbol comes to mindyeah, tomorrow
with the Flamingo, we got a packet of what looked like Jelly Crystals.........for cleaning or something...
silver foil packet with blue on it is all I remember
