Hi I have the manufacturers name moulded into my campervan's pop-top fibreglass roof but I would like to replace it with the campervan's name PHILEAS.



I will just sand it off so will have to make it slightly bigger to cover the sanding I have purchased chrome letters that you put on the boot of cars, in order to make a mold from but have no idea how to do it or products to use. HELP!!



Here are my letters I bought





The original is on a type of plinth aswell any pointers gratefully received.
