Guys,

Thought I'd share this with you. If this is already common knowledge then disregard. I have been using UGL 222 Lite spackling as a filler for many years. I bought it for a home improvement project and was impressed with how light the container was. Working with it, it appears to use microballoons. Sure feels like it. It dries fast, takes paint well and is super easy to sand. The olive drab Sig Mustang fillets were done in 1992 or '93, and after all this time and a few more hard landings than I'd like to admit to the fillets are like the day I made them.


Might not be everyone's cup of tea but it works for me.

I found it may dry out after 10 years or so, so simply add a little water and stir... good as new.

I need more Nitro!

My choice of fillers in order of preference:
1) Leather
2) West System 105/205 combo mixed with microbaloons. I keep adding until it can't take no more and starts to heat up(cure).

If it's what I think it is, watch out for shrinkage.

I prefer Superfil.

I use DAP Drydex for all filling, except for fillets and then I use SuperFil.

You can get some tensile strength into all the hardware store light fillers.  Just add about 1 tbsp. of water-based varnish to one cup of filler.  You'll know if you added too much because the varnish will settle to the bottom of the container.  It can be remixed easily.

The 222 stuff might be a localized brand.  I've never seen it on the East coast.
