I've just doe a fsg . Now there was about 5 metres above the conny which was awkward to clean . I sprayed some chemical on the wfp brush and it got the thick off , but there was some striping on the fascia it wouldn't shift . So I got my trad pole out with the applicator on , and fastened a magic sponge on top with a rubber band . It did it ok , but,is there something that fits on top of the pole which you can buy to make it easier. Cheers.
