Well applied the hull upper grey, after the grateful advice from Tim, the seams are a lot better but room for improvement! But more confident now thanks Tim!
It's a pleasure to work in the new room, no drafts, dead insects, dust, cat hair etc, praise the Lord!! finally no dust or dirt in the paint.
Dare i say, really enjoyed spraying and in my opinion it looks good!
Will leave for a day then mask and spray the dark grey on the lower hull, not using the correct colours but some spare Mr color.
Thanks to a idea from Mr Race I have ordered a ducting Y splitter, sounds painful lol, also found the vent end to put out of the window. So will shortly sort out the 2 into 1 vent pipes.
