When I was picking up CA and other items for my first build I added this WHITE PUTTY. Has anyone used this,will a covering stick to it?I have saved my balsa dust to mix with yellow wood glue knowing there would be some voids,dents ,dings. I forgot that I had this putty.Is this putty some thing that can be used and not have to worry about? pub

I am not sure what it is that you have. If you are just wanting a filler for dings and cracks, you need a something simple. I use a product called Paint and Patch, which is sold in the Home Depot paint department. It runs about $3.00 for a tub of it. It sands easily and fills perfectly. Good Luck, Dave

I've used Squadron Putty for years with good results. However, my applications were limited to filling cowls and landing gear pants. Basically, it's similar to Bondo. I have never used it on balsa.

You will probably find that it is too hard to sand on balsa. The balsa will sand away around the putty, and leave the putty as a high spot. Light weight vinyl spackle, from your Home Depot (or similar store) works quite well.

i know what your talking about i think i use the stuff all the time it sand great and covering has a tendensy notot stick if you use it as some sort of structural fill or construction its actualy made of ballsa the stuff im talking about its tinted white for perpuses of seeing where its been aplied. you should be good to use it on small cracks and holes.

Thanks , sounds like I'll be making more work with the putty and covering not sticking well,I'll stay with the glue and dust. pub

It works fine for filling in fiberglassed models but not sure how it works on balsa when applying heated covering to it. It's very similar to the acryl spot putties used in the auto repair industry but a bit less runny. Plastic modelers use it all the time to fill voids in their assemblies. It sands fairly easily, dries quickly and you can scribe lines in it. I've used auto body spot putty, or glazing as it's sometimes called, to fill small voids in planked fuselages and that worked fine.

The thing that most people make the mistake of doing when sanding is they use too fine a paper so they end up polishing the hard spots and sanding down the softer spots. If you use a fairly rough grit like 60 to sand the putty down, you'll find that it comes off just fine and when all is to approximately the state you want it, than hit the whole thing with 220 to get rid of scratch marks. You'll be glad you did.

Squadron white and green are used regularly by plastic model builders. I've been using it for years on static cars and planes, and it has never cracked. I'm not sure how well it'll hold up to the vibrations on a plane though.
