>>11237248>Mr surfacer 1500 white was the white primerMr Surfacer has some issues sticking to stuff other than regular PS, so I would not use it as a primer. MrColor used to make a special resin primer (which you can't find anywhere now), MrPrimer 1000 should work, although for UV resin I would recommend Tamiya primer.
>Mr hobby' blue liquid mask.Both of Mr Hobby liquid masks are blue, but one (Neo) is latex and pic related is water soluble. I would only use peelable latex masking for masking painted surfaces. In any case, washing in _hot_ water serves no useful purpose, if the mask is water soluble it will dissolve in room temperature water just as well and if it is latex, wetting the mask will make it harder to peel.
>struck to the tiny dips between the 3d printing layerThat's why you keep sanding and priming with coarse primer until they are gone. There shouldn't be any visible layers by the time you are ready to paint.
