Sandable filler?
 
What do the experts use as a filler to make a wing repair looking like new?

I am not so happy with the bondo/easy sand auto body filler I tried. It is also pretty heavy.

One of these any good?

West System 410 is a good product and much lighter than Bondo when used with the West epoxy and hardener. It's light brown in color when dry.

CST carries it.

Happy sanding,

Mike

+1 for the 410 with West Systems. "Dryer" mix is more sandable, wetter less, but stronger and heavier. Bondo is for the PSS cavemen, where heavier at all ends is better (they think).

If you REALLY want it light and strong, under-fill a fillet a little, and lay on some light glass. When it gets tacky, add the finish layer that you will sand.

I really like the Superfil and use it almost exclusively. I have since put away the epoxy and microballoons unless I need a really wet mix or want to put in fibers. Good for both dry and wet sand, really good with wet sand. I'm on my 5th project with it. Nice working time, a little slow, but I put some in the hot box last night and it was easily ready to sand in the morning.

Most of the filling I do with epoxy is for internal work and uses chopped fiber in place of microballoons.

I also keep some lightweight spackle on hand for the last foam fill before bagging.

Split Second filler is the best I have ever used. It is liquid microballoons suspended in the can, SUPER light weight, fast, and sands so fine you can polish it. I get it at my local automotive paint store in Long Beach. Once you use it there is no going back. I can post a picture of the can if needed.

I take it split second is polyester based, meaning no foam cores?

#11 fcbflyer Feb 20, 2011 12:47 AM

On foam cores I would only use lightweight spacle. Trying to sand anything harder then that will Be nearly impossible.

+1 for Spackle, its so light and easy to sand.

I'll have to try the Superfil and Split Second stuff.

Thanks,
Target

Here is a picture, G.E. Paint (Gary Elliot runs the place) is I think on Anaheim street in Long Beach just east of Junipero, it is around $25 a can, the can feels almost empty since the stuff is so lightweight, it is just a lttle thicker than whipped cream.

Thank you guys to chime in here. I did the 410 epoxy mix before and didn't like it too much.

I ordered a can of split second and will report on the outcome.
