Hey guys, I have a question regarding CA finish on wood. I have tried this several times using a Devcon product which is very thin and experienced a haziness or cloudiness in spots in the finish. The process that I have used is to quickly coat the wood, let dry, and hand sand to 600 or 800 grit, then buff using white compound. Parts of the finish are crystal clear and look great, but some areas are cloudy. What can I do differently to avoid this? Thanks.
 
It could be blush, which is something you get with clear epoxies. Clean it with water and a bit of soap and wipe dry BEFORE sanding and buffing. Sanding and buffing just push it into the finish.
 
To get the deep luster superglue finish, you need to apply 15 or more coats. Scott Slobodian may uise 30 coats for his pieces and they are beautiful.

When you start to sand it all off, after all the coats have dried, it will get gummy and then clear. Once it's past gummy and clears, it's hard and beautiful. Scott's finished look an inch deep.

is it an actual layer over the wood or does it sand down to the wood? for whatever reason it seems like a coat of it would crack and chip. i will have to try it out.

It's both soaked and a layer, Gene covered everything that I was told by Scott except that he uses accelerator. For what it's worth, I read he only uses CA and accelerator from CPH International. I've talked to them and read their literature and it seems very good. Their glue does not break down in water, which is supposedly not the case of some super glues.
 
Thanks for the information. I usually wait until the last layer appears dry, say 15-20 minutes prior to sanding--that may not be long enough. The cloudy layer is throughout the finish and will sand down to the wood. For some reason I have noticed it mostly on cocobolo. Another possibility may be that on cocobolo the CA builds very quickly(not soaking in like on softer woods like maple) and the increased thickness of some of the layer might cause it to dry coudly.
 
I betcha it's the accelerator that is key. Probably keeps it from soaking in too much.
