What filler do people use for plastcard

I use Squadron White Putty. I found the Revell stuff doesn't adhere too well.

Like Rik, I use Squadron White.

I've used Milliput standard (yellow and grey) filler without problems.

Squadron White. You can't beat it.

The other stuff is rubbish. Revell and Milliput don't stick.

Can this filler only be used on plastic?

I was wondering if it could be used on brass?

Not used it on Brass Tom, but it's fine on wood too.

I've used it for filling very thin cracks in brass joints, as it can be thinned with MEK and brushed into the crack. It won't stick very well to brass or steel, so is fairly useless for filling surface defects like scratches and dents.

I usually use solder as a surface filler for brass and mild steel, although I've really never mastered the art of lead wiping.......

Never really found a great way to fill holes in brass (small bolt holes).

It depends on the access. I either use a blob of epoxy putty applied from the back, then filed and sanded smooth when hard, or use a rivet. My preference is a rivet, as I dislike handling epoxies.

This is what I want to tackle:


Small bolt hole and if possible the gap (these would of been using for the hinged roof Roundhouse use but as my roof uses magnets I want to tidy this up).

The paint work needs doing again so isn't an issue if damaged in the process.

Tom, I would have no hesitation in using Milliput to fill both the hole and the gap, but first you need support from behind and I would use a small piece of brass angle either epoxied or soldered inside the cab. The location there means it will not show afterwards.
Milliput is easy to apply and can even be smoothed with a little water before it sets.

I modified the hinged roof on my Roundhouse #24 and had to fill in the same sort of holes, but can't remember how I did it. Most likely I used solder.

The cab walls are thin metal, so not much surface for a filler to stick to. As Peter suggests, you'd need a thin metal backing inside to support the filler if you were to use epoxy putty like Milliput.
