Time for an update - I finally got some time last weekend and have sprayed the first coats of acrylic. Thanks to phrozin, who I PMd with some questions, for his extra tips on how to do it - much appreciated mate.
So bit of a mixed bag. I erected my BCF-special outdoor dunny-cum-spray booth in my back yard, and hung the body up inside. By the time I'd done all the prep, it was a bit windy. I gave the body an ultra-light sand, basically just dragging some 600 grit over it without any pressure to remove the hair and then I blasted the body with some canned air and a large soft-bristled paintbrush to get rid of the dust. All looking good. Sprayed the three coats with a 5-minute wait between for flash off.
But after I'd finished, I realised there was some dust in the finish, especially on the back of the body (see photos). At first I thought it was the wind kicking up dust that got into the wet clear, but after thinking about it for a while it looks like the overspray mist that the booth was full of has sort of crystallised or dried into these snowflake-like things, and that's what is stuck to the body. After it was dry I took some photos but you can't really see them very well. I'm hoping that the sanding I'm about to do before the next coats will remove it. Anyone seen anything like that before?
Also wondering if I've done enough to start wet sanding? I used about half to 2/3 of a can (400g Septone from Super Cheap).
Unfortunately it's hard to see those dust/flakes in the photos (none on the front that I can see, all on the back).
Apart from that, it doesn't look too bad. Obviously needs a lot more coats but if I can get rid of those flakes, it should be ok.
Oh yeah, one other thing, that wire is good enough to hang it from, but bloody difficult to control when spraying. Might have to screw a piece of wood to the neck pocket - what do you reckon? As it's a set neck there aren't any bolt holes, nor will there be in the finished product.
