I'm after a creosote-type covering, that will last forever ...... well, maybe not quite that long !!
I've just done 2 panels in Creotreat:

.... and I'm about to run out.
Now apart from not being able to remember where I bought this from, I'm wondering if this is up to the job or not ??
Anyone any advice as to any suitable products out there .... I don't want to have to keep re-applying year in, year out ??
