Help getting a nice smooth surface

[joe58]

Hi

Are there any products that can be painted on and sort of self level or just is thick enough to fill the really annoying little pits? This is where I just can't quite get the filler to smooth off between the two Blanda bowls. A picture tells a thousand words, although not as bad at a distance that the camera makes out. Also will these imperfections start to disappear when the proper paint is applied?

Thanks

Self leveling on a sphere wont work very well. The only thing iI can sugest is the old fashioin sand paper and many coats of paint. Maybe someone else has abetter idea.

Automotive spot putty!

I was thinking of the Polycell Smoothover, but it appears you roller it on and then use a large paddle to smooth it off, which wouldn't work with a sphere.

They also do a 3in1 Problem Wall Primer, which could be like a 'thick' paint. I'm hoping a 'thick' paint could help reduce the imperfections.

I was trying to keep away from stuff like putty as I've been doing similar stuff with filler. However I do have some Milliput I could try on some areas, but still would like some paint style stuff.

I see some random scratch marks on there which seems to show that the surface is on the soft side. I have used multiple layers of kills and wood putty, but was frustrated with the delicacy of the surface. So frustrating!

If you can stand the fast working time, and general messiness of fiberglassing epoxy/Bondo automotive body filler, they are way easier to work. Their rigidity makes them really easy to shape and smooth.

Having a paintable solution would be nice, but paints tend to be way too thin to do any serious filling. Even with thick coats of epoxy I had to fill with bondo to fill many imperfections. I think getting a beautifully smooth surface just takes a lot of work :/

I'm not to fussed about the hairline cracks, it's more the slight pits in it.

Has anybody used High Build Primer? Linky. It talks about having a thicker coat than normal and being able to cover small surface imperfections. Is this what I've been looking for...?

Just to keep up to how I'm getting on for people that have similar problems. I got a tub of Polycell Base coat. The first coat is on, so I'll report a bit later to how it's dried and if it's solved my problems. First impressions are quite good, although that probably has sealed it that it won't work...

Feather fill primer. Its an automotivr product. Check for compatability.

I was looking at another High build primer and it was for metal only. Can you get that stuff in a aerosol can, as I don't have a proper sprayer?

A quick update. here's some images of the basecoat applied. This is after about 5 coats(lost count) and it seems to have done as I wanted. Not perfect, but better than before. Although I will have to go over with fine sandpaper and get rid of the orange peel left by this type of paint and the roller before the primer goes on.
