Im currently using tamiya white for my filler, but im wondering if there's anything better on the market

There is.... Tamiya Grey...hahaha..

Seriously, I have 5 different fillers, from thick super glue, to AV white and they all do different things. You have to consider the size and dimension of the space ( is it a hole or a lip edge) and how easily you can get in there to sand off the extra. If its a seam, does your filler have the ability to flow or stay in a thin straight line as it comes out. Tamiya putties are my favorite right now as they are durable, sand well, and set up relatively quickly. I also have squadron white and green, and have similar thoughts about them alothough the green tends to be more durable than anything short of superglue. Mr Surfacer works as well, and can be laid on in a thin bead. For my experiences, the AV putty is the softest of them all and takes a really long time to harden, if it hardens completely ( might be a bad batch too). BUT, it has the added advantage of being one of the easiest to clean up... plain water while its still wet will remove excess and make sanding almost un-necessary

Bondo Red Spot Putty. It does it all. Can be thinned for tight seams. Creamy and works easily. Covers large areas without cracking. Sticks to all materials. Sands glass smooth. A $5 tube will last you years. Available at Wal-Mart or any auto store.

I like Mr Surfacer 500,just brush it into the gap,after it dries,I remove the excess with alcohol and cotton swab.Just don't wait too long.

Either Bondo or Mr. Dissolved Putty. Bondo allows you to add bulk. However, it may be difficult to sand and you will create quite a bit of dust. Mr. Dissolved Putty(now that I figured out how to use it) is great from shallow depressions and narrow gaps. Just let it dry for thirty minutes and shave the area with a razor knife. No sanding, no mess(except the shavings). Also, if you want to go cheap, you can use white school glue for filling the shallow depressions and narrow gaps. Treat it as described with Mr. Dissolved Putty.

Jonas,

I was a fan of Bondo putty until I tried Perfect Plastic Putty.

The name says it all.

I am a big fan of Perfect Plastic Putty as it is easy to apply in both large and small quantities and sands very easily. The putty also takes detail that needs putting on it and takes paint very well.
Perfect Plastic Putty

I will add that there is a place for many different types of filler depending on what it is needed for.

Just ordered Perfect Plastic Putty. Maybe I can replace the heavy handed sanding needed with Bondo.

One thing i have started to use with Perfect Plastic Putty is a hypodermic needle and syringe. I liked the inclusion of a nozzle, but I found I wasted a lot of the filler. I have found that using the needle and syringe has enabled me to add very small quantities to very exact locations.

That is one thing I like about Gunze dissolved putty. It is easy to apply in small quantities and only takes a couple of applications for large spaces. What I truly like about it is that you don't have to sand it.

Give testors contour putty a try . Nice small diameter nozzle lets you put just the right amount of putty , and is real easy to work with . It can be cleaned and shaped with Tamiya lacquer thinner before it fully dries .

I like Perfect Plastic Putty its creamy, smooth,no odor,dries in minutes, easy to sand and it doesn't shrink...... Good stuff

You must remember to be careful, with the lacquer thinner.

The Tamiya lacquer does not eat the kit's plastic . Too much might remove the putty but if you have a light touch it won't mess with anything . Mr Color thinner works also .

Tamiya putty thinned with their lacquer thinner if needed for most gaps.

Mr. Surfacer or Tamiya liquid surface primer for small gaps or imperfections.
