What kind of saw is it? And I find that silicone sealant works the best //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

MDF dust and glue, then silicone over that.

resin

Resin with filler. Resin byitself just leaks out

Why would you use wood filler for that purpose? It isn't meant to seal anything, just level out the surface. You could use silicone on the inside and wood filler on the outside, but it'll still look interesting.

one of the gaps on my ssd box was pretty good size. table saw was buried so i used a jugsaw to cut the whole box. after the normal caulking all the seams it didnt take too much more to fill the gap. ghetto. but worked.

His question was what is the best way to fill cracks in a poorly made box? Well there many answers to that depending on just how poorly u made it,lol. If it's a small crack wod filler would do just fine. Also, how r u planning on finishing the box? I read on here yesterday some guy that claimed he was all that & a bag a chips when it comes to car audio was going to fiberglass over MDF, well that told me how smart he was right then,lol.See if u wanted to have ur box look & feel just like fiberglass u can buy some Low-Build Primmer & apply about 3 coats, sanding between all three. It will harden just like fiberglass & will form a hard shell that will fill ALL your cracks, but u should always seal up the inside around all the jionts with a LATEX based silicone, latex means u can clean up with water instead of making a bigger mess,lol! Now I take it the cracks u r refering to is actually huge gaps in-between the pieces of wood, where u put them together. If thats the case that tells me you don't have enough glue holding it together, glue is the most important thing that will hold a box together, see once the glue cures properly u would actally tear the wood before u would break the glue joints! Lots of glue should be used along ALL places where wood is being joined together. Now someone said use resin, well I would NEVER use that junk, it stinks and is not the best thing for the job. The absolute best thing to fill even big gaps in wood is something called "Durham's Water Putty"! U can get it Home Depot or Blowes & it comes in a can in a powder form that u mix with water then apply just like Bondo. This stuff will dry HARDER than even Bondo!! It will bond to the wood perfectly & u can sand it if needed. Just get some and put it all inside ur box after u seal it with caulk and it will take care of the cracks. You can get it in the paint dept. I even looked up the link for u so u can check it out. I have been a carpenter, interior trim,framing & cabinets,for over 20yrs now & have used this stuff many times. All the pros use it.
