1199R Brushed Aluminum Tank Sections
Posted by Nezil on Tuesday, March 19, 2019 9:40 AM

Anyone have any ideas on how to recreate the brushed aluminum sections on the 1199R gas tank?

I have the Hiroboy decal set and the kit waiting to be started, but this section alone is putting me off... I'm thinking about lightly sanding in one direction, purposefully leaving sanding marks, then hitting it with Testors Plate Aluminum, buffing, then 2K clear over the top.

The issue is that I've got to try and do this with Red in other sections, and I don't think metaliser will survive masking, so it needs to be done last, with the Red sections masked.

I'm hoping this sort of finish isn't that unusual on 1/12 bikes, and someone can chime in with a possible approach that might work?

I think I would attack it like this;

The area to be finished aluminum does not appear to have a heavily brushed appearance. As you mentioned, I would lightly sand the area with fine sandpaper in one direction, then spray the aluminum metalizer. The metalizer will easily show (magnify?) any surface imperfection under it, so the 'surface pre-brushing' should work well. Once the aluminum is buffed, it should have a nice brushed appearance. The red painted area will have to be masked before the sanding, of course. Be sure the red is well cured.

You can try brushing the already applied paint with a fine Scotcbright pad or similar, but I think the effect will be better as described above. I find doing the 'aluminum brushing' after the paint is applied darkens (oxidises?) the aluminum, giving it a less realistic appearance.

If you apply a clear coat afterwards, you will lose the authentic aluminum appearance, and it will look more like silver paint. Even the metaliser sealer diminishes the metallic effect, but I think a glossy or shiny clear will ruin it.

As always, try the process on scrap material.

Others may chime in with better info. Just a hint, you will probably get more traction on this post if it is asked in the 'Paint & Bodywork' section of the forum.

Thanks @Bainford. Will consider posting in the 'Paint & Bodywork' section as well.

Here's an image in case it helps:

The problem with Metalizers, as you likely know, is that the surface can be delicate. It also may be difficult putting a Ducati decal on the aluminum Metalizer. The carrier film will likely be quite visible. Hhmmm... tough surface to deal with. At least it is a buffing Metalizer, which should be easier to deal with.

Wow!  No fun. What about masking more than once? Once by covering over all the parts the will be red; sand the exposed areas for the brushed aluminum, remove the tape from the future red areas and mask over the brushed aluminum parts then spray your red. After that, remask the painted red areas and then do the metallizer. Its a long process but I think the end result would be well worth it. ( I think )  lol

ever thought about using and automotive paint, 1000 grit sand paper and paint your red right over top. Atleast this way finish will hold and you can put a few coats on so you dont sand thru.
