servus leudde! after three years finally found time to install my b-cadet new engine. after the part is now standing without a cardan shaft on the pit, it is possible to completely renew the underfloor protection. rust is not there at all :-)), but partly the old bitumen mass of the sheet. a few years ago I sprayed it from below completely with wax. in the next days I would either use a scraper or a wire brush the loose stil Is there anything better than bitumen spray? The other day I found plastic scar in the factory. the article kept relatively good on the inside of the protective sheet of my sr500. that’s why I thought maybe to work with it..? -> please write what you have on the bottom and how you get the old cracked layers down.. thanks a lot! scr
