Last week I try to make what I belived was an improvement on the finish of the guitars I build, so I switch from Nitro to Poly. I tried a test make it brushed but after several coats had to buffer it and the shine was lower than the actual raw material (by the way I`m in Costa Rica so a lot of the brands and products mentioned on some forums are not available here). Then I bought a little re-touch spray gun as working with guitars are very small areas, then after about 4 coats the poly showed some pinholes, I decided to let it rest and see what would happen. WRONG!! I checked the guitar 24hours later and it was full of blisters and bubbles; like the face of a pizza teenage guy. If anyone can help me on any advise on the technique it would be welcomed.

Hi I'm in my polishing phase for my new guitar and after using the compounds found some little dots like dust in my finish, from distance it looks like some part were a little hazy but very close seems like tiny holes in the finish. DOes anybody have any advise in to eliminate this problem, would be great. Thanks

Thanks to all for your comments; The veneer I'm using is 1/42", I could make it work with an iron and a sand bag going one by one bubble. Thank You for the tip eljib. It seems it worked perfect until I was in my 4th laquer coat, and it seems one of the little bubbles (about 1/32 x 1/4) wont give up, it looks like if a hair had fall on the wet coat. I'm waiting for the laquer to dry a couple of days and sand down all imperfections with 400 sandpaper and then 800 to apply 4 new coats; maybe I could lower the bubble. If anyone can give me a good avise on how to proceed would be great, I don't want to sand down to much and make a hole or iron again and melt the laquer coat, but I think it is the obvious way to work it out. PS: If someone can teach me how to upload and image I think it would help, I searched on the help but could find it.

Hi, I'm trying to make a guitar based on a Les Paul desing, this will be my 3rd project, but is the fisrt one applying a veneer top. I tried to follow all the indications, the problem is that the body had already a sealer coat, I did my best removing it with my sanding machine, but some part still showed some sealer marks, I didn't wanted to compromise the carved top so I moved on, glued the veneer in four mirrored panels, let it dry for about half a day. Some bubbles showed on the veneer (most of them in the joining lines), so I heat up my iron and did my best (I read in some posts that ironing veneer is a good idea). Everything got better and mostly all the bubbles gone away. Very pleased I went to sleep, and this mourning when I woke up the top was again full of bubbles making fun of me . If anyone can give me a got avise about it, will save my day. I think maybe try again with the iron (not very hopesly), or peal the veneer sand all over again fully removing some sealer that maybe is hidding somewhere (not very easy). All your comments will be apreciated.
