Puttied/Sanded Area Finish Not Right
Posted by DaBarge on Wednesday, January 20, 2010 9:51 PM

Hey all

New to this stuff and cant figure out really what the problem is here, so thought I would see if anyone can help me out.  Working on a turret of a 1/35 M41 Walker Bulldog.  I put on a couple coats of Tamiya Spray Olive Drab and noticed the top half and bottom half had some bad fitting areas (this area of the bottom half jutted out a good ways).  So I sanded it up (up to 800 grit) and puttied up the seam and tried recoating it with another 2 coats of OD.  You can see the area to the right of one of the rungs.  Is it just not enough sanding with a really fine paper?  Thought I would check to see if anyone knew what my problem is before I ended up trying other stuff and ending up with 50 coats of OD on the turret Big Smile

Thanks, Shane

Maybe try going over it with a light coat of LSP followed by an 800 grit then a 1200 grit...

I could use some more sanding.   If I putting an area I always prime it before painting.

I'll add that you should always "wet" sand, using progressively finer grades until the putty is nicely "feathered" down to the surrounding area. Hold the sanded area up to the light, tilt it at a slight angle and look along the seam  for shadows or highlights indicating unevenness. Sanding seams/putty is one of those tasks requiring patience.  Don't rush it , take your time and you will be rewarded.

definitely need to prime it. or put a coat of future over it. otherwise it will always show through

800 grit is more than fine enough. that's what i use on my cars and it doesn't leave scratches.

Presunably he's referring to Tamiya's Liquid Surface Primer, which is similar to the finer grade Mr Surfacer.
