MR Hobby Base White 1000

[av405]

Have any of you ever used this as a barrier with a kit molded in black or another bright color such as red? Is it effective at preventing bleed through?

Also, what's the difference between the Base White and this:

I have the air brush version and it'll take about 3 coats to cover, but you wont get any bleed through like you could with the regular version primer. It's not the same as there surfacer, but can be used the same as surfacer, and it's more pigmented than regular surfacer. Here is a quote about the product:

Mr.Base White is useful for making a black, red or other dark-colored surface white. This newly developed product uses special pigments to completely hide the base color and aids application of detailed finishing and top coats. Because it also works as a surfacer, it can be used to hide small imperfections.

I’ve used it in the past. It does cover dark surfaces well, but I didn’t think it worked well as a primer. It doesn’t seem to stick to plastic as well as Tamiya or Mr Color primers, and rubbed off easily, taking the paint with it.

White doesn't work to prevent bleed through. You have to apply too much of it.

I don't know why this works, but if you have a kit molded in a color that you don't want bleeding through, grab some silver paint in a spray can. I use Tamiya paints.

Spray all the parts in silver. Just a couple light coats will do. Then prime and paint. Works every time.

Thanks for the 1st hand account. So you did the base white and then added primer? Or what were your steps?

Thank you. So do you recommend spraying primer first, then this, then primer? Or the Mr. White and then primer?

You could go over it with regular primer weather it's surfacer or tamiya, but base white can act like a primer it just doesn't have the same filling properties as the others.  I applied it same way i would surfacer - basically roughing up the surface 600 or 800 grit, and applied it the same as surfacer and it sands the same.  Never had a issue with it rubbing off as it's basically surfacer just highly pigmented.  You could go the silver route as well.
