What are you guys using to take care of small dings and the like during the primer coats? I have some stuff made by 3M (same stuff Windy used on some of his past videos, green in color). I think my tube is to old to use, doesn't want to stick when spreading and hard to sand so I'm going to need to pick something up.
Thanks,
James <=

Bondo makes a red spot putty that costs about $3 at Wally World. It works pretty much the same as the 3M. It's in the automotive section.
FORGOT TO ADD: you can add some acetone to the green putty and use it for short term. It dries out (looses it's carrier), but the acetone will reactivate it until you can get some more. I have also used lacquer thinner for the same purpose.

I agree with Bill..the red bondo is good stuff...cheap, dont have to mix it very precisely, and it "kicks" in 5 or 10 min. easy to work and sands easily..I used to use it on fiberglass and gelcoat for boat repairs..good luck, BOB
-
AND: Bondo also has a small tube of glazing putty that doesn't need mixing. I use all kinds of stuff as long as it works and isn't too heavy!
Mix micro ballons with Elmer's Glue All, balsa sanding dust with Ambroid, or white glue, etc., etc.,

I use Elmer's Carpenter's Finishing Wood Filler for light woods. It is a latex based light filler that is a little more yellow than balsa. It goes on very easy, sticks like glue, and is very easy to sand. It can be feather edged with a finger dipped in water, is light weight, and works well under translucent yellow dope finishes. I like it!

It's what I use too, but I always hesitate to mention it for fear of giving someone on the board a heart attack...

James,
During the primer coats I use Bondo brand glazing putty. It has a reddish color to it. Wet sands very easily and feathers real well too.

Be careful of the spot putty. The stuff never stops shrinking. OK for very light scratches and such, but it will crack eventurally if used in too large an area. I use a catalzyed spot putter called glazing compound (I use soem stuff called Dolphin Glaze). Works and sands pretty much like the old spot putty, but it's catalyzed so, once it cures, that'ts it. What you have is what you have. No concerns about shrinkage.
-
Good reccomendation Randy. another benefit of catalyzed glaze, it is fairly inert to solvents. With the one part glaze, whenever you spray laquer,(dope) on it, it will swell and then reshrink, not a good thing for that peachy pretty finish.
