So I prepped as much as possible, I used a whole litre of wood glue, plus some water and dye to cover the whole dashboard, just! Then Flocked it.
First thing is i did this by myself if two of you were painting on the glue it would help and speed things up and give you more time to work with. However so far I'm happy with the results. So Messy though! going to have to spend a fair while cleaning the spare room.
I've now left it to dry and see how much of the flock holds. This will be the biggest object I've done and it was hard work to get right and done before the glue starts to go off to much.
A couple of things to note, once my batteries came loose and that might mean I have a flatter area although i hope not! A good thing though is the glue hides scratches that are quite deep so you don't need to sand to a totally flat surface
And finally always switch it off when reloading and zapped myself twice, quite a hit for batteries! but at least I know it was working!
