If you have a hole you need to fill in HDU, what do you use? I have been using wood filler, but when you go to paint, it leaves a big "slick" spot where the filler was sanded. Very noticable. Me no likey .
Any other suggestions?

I have used another piece of HDU, drill out a hole the size of the patch and make a piece to fit in. Glue it in so it sticks up a little, then sand it down, the tighter the fit, the less noticable it will be.

But what about a litle screw hole?

Jake, How about adding some HDU "dust" to GG or maybe Titebond 2? I'm just guessing here. Think I'll go and drill a hole in a scrap piece and give it a whirl. I'll let ya know.......

Spray foam insulation?

I just read if you prime BEFORE you patch it won't be as obvious (and then reprime, of course...) Cat

Hey Jake! I have done with gorilla glue, it work great. I usually mix couple drop of water in a small cup and GG and apply on the hole let set. then I go back with a razor blade and trim what has expand. then sand , primed and paint. I hope this helps...

West System Epoxy with their low density filleting blend added, makes the epoxy sand at the same rate as the foam. If you need it I can get the numbers off the lo density blend.

Small holes we use Baking Soda and Superglue. Fill hole with Baking soda then add a few drops of superglue. Puff of smoke then sand.
Larger Holes Same as Ken WSE with filler..
haven't had a chance to try Sals Formula but saw him do some stuff at NH meet.. was real interesting

I just knocked this out with a plug cutter on a drill press. Viola! HDU plug. Posted by jake snow (Member # 5889) on :
Thanks guys, I'll be printing this one to try some of these in the future. Thanks again!

Jake,
I don't have much experience with this, but I'm pretty sure Nancy Beaudette covered this problem in a HDU demo in Moncton. She said to do all your priming and then fill the hole after. This gets rid of the smooth spot. Give her a call and see what they use for filler.

Quick wood epoxy available from Canadian Signcrafters in the merchant section. It comes as a two-part stick that you mix by hand. It sets up in a couple of hours and has a shelf life of at least a year. Spreads like putty and sands drills etc.

Jake, here are parts of an old post with the same question.
Here is a method I used recently to fix a goof-up I did on an HDU sign.
This first photo shows the groove (originally a "v" groove) I routed in the wrong place. (you can see the guide lines to the left I should have been in). I re-routed it with a flat bottom bit.
The next photo shows a "key" I cut-out on the table saw. I kept it as tight as I could, and let it sit a little proud (high) of the surface.
The last photo shows the "key" epoxied, and sanded flush. The slight imperfections aroung the edges were easily filled in with primer. It was barely noticible, even if you were looking for it.
This works well for a major mistake, but could also work well with a big "ding" or heavy scratch.
I agree that it never seems to match if it's filled with bondo, or the likes.
