First Build - JBA-4

[Simon Barden]

Good news.

I'd sand the clear back flat as much as possible before spraying the edges black. It will make like so much easier when sanding the final clear coats. You'll also want the surface to be slightly rough (say P600) so that the fresh clear will adhere to the cured clear. There's no strong solvent in acrylic, unlike with nitrocellulose, so the new layer won't melt into a cured layer, it will sit on top. If it remains shiny, there's not a lot for the finish to grab onto, and it can delaminate over time or if knocked. So a sanded surface is much better for the acrylic to grip to.

No, I would leave it alone Simon, I'm expecting the black not to work as he's using a black rattle can for a burst I would put 6-7 coats of clear before the burst so if he has issues he can recover the clear with light sanding ideally not spraying a burst with a rattle can as I've never seen a burst look ok with a rattle can, doing a burst is really experienced builder territory with spray gun or airbrush, if he has used a filler with wood putty why does he need a gluboost i have heard of gluboot but isn't it just a clear CA glue I use CA a lot as a grain filler if I doing a colour finish i think Mathew has read so many versions that he's a little lost with this one but I get what he's trying to do with this build, I guess if it goes west on him he could sand it all off and start again but I think for this one with his dye would have been better with tru oil on this one as its almost fail proof

Matthew trying to do his best and he's learning and he's asking the right question
