Hi I have moved into a house with quite a big back garden.  The fence is painted/stained a (quite ugly!) reddish brown colour.  Also some panels have worn and been replaced by the previous owners but these are bare wood. I have a had a new fence put in the front garden so I bought 50l of dark brown creocote, with the intention of doing the new front fence and the old back fence. Sprayed on a treat, front fence looks great. However, even after 3 coats it has not covered the red in the back.  It's barely coloured it at all. Any suggestions on how I can tackle this....problem is I've now got several nice brown panels in the back and the rest this horrible red.  What can I do!?!!? Thanks....
