Materials so i got my clay

first you shouldnt worry about what to seal your doll with when your just starting to make a bjd, thats like one of the last things you need to worry about. Your in for a long road. For primer i recommend car primer, ive read it works the best. For a sealer im not sure, i think shellac will do just fine. It also depends on what type of finish you want, If you prefer a matt finish or shiny. After you spray the shellac you still have to sand it and polish to make it nice and shiny im not sure if you need to sand it after spraying shellac but this is just info ive gathered from research.

 

ok ^_^ primer is the stuff they spray on cars before they paint it, it allows the paint to stick to the object and not peel off when its dry. Primer is color gray and needs to be sanded to get it smooth. You only need to use primer for when your done sculpting, then you spray with primer, then sand away. The primer will let you see all the little mistakes that you dont notice in the sculpt, so just sand it away until its smooth and even.

Sealant is sprayed after the object has been painted or it is completely done. Sealant will seal the object so that it protects the paint or sculpture from stuff like scratches and water and also makes it shiny if you sand and polish.

You dont want to spray sealant at all unless your sculpture is completely done, because then it will be covered in a layer of sealant and you cant paint over it, it will look bad.

If your buying primer get car primer, if your buying sealant and want a shiny finish get shellac and make sure it doesnt say the word matt on it. Matt means it will seal the object but it will not make it shiny.

 

It sounds like you have what Twigling talks about here: http://www.denofangels.com/joints/showthread.php?t=4508
If so, it should work fine.

 

marita it sounds like the right stuff, I think the description on the box refers to how you would use it if applying it to a car, where you definitely would put another primer and then topcoat over the top. Just make sure it is an aerosol can, because you can also get another filler for car bodies, which comes in a paint-can, and you buy the hardner separately in a tube, mix it up and get a thick and very smelly (fast setting) putty ~ this you do not want for your dollmaking!!

But for dollmaking you just need the "cover uneven surfaces" qualities, so do a couple of coats and then sand with 400 grit wet sandpaper. Make sure you have sanded the surface to 120 grit dry and then possibly 240 grit before applying the primer/putty.
