WezV Posted April 13, 2006 Report Posted April 13, 2006 Some weird bubbles have appeared in the finish of my bass as it was curing. Anyone had a simlar problem and has any ideas what might be causing it Quote
Racer X Posted April 13, 2006 Report Posted April 13, 2006 What exactly is under the metallic paint? Quote
Nitefly SA Posted April 13, 2006 Report Posted April 13, 2006 are you sure they are bubbles and not just painted over debris? did you thoroughly clean your painting surface before spraying? Quote
WezV Posted April 13, 2006 Author Report Posted April 13, 2006 Yeah its definately not painted over debris. Heres whats happened with the finishing so far: 1. Grainfill with epoxy 2. White primer 3. Metallic green (cellulose i think) 4. Clear lacquer (Acrylic) The bass was just about done but when we came back to it bubbles like the ones in the photo had appeared. We decided this was probably because of an incompatability between the green and clear lacquer. The front of the bass was fine so we decided to spray the back with metallic grey that was definatly acrylic and should match our clear. We also added a black stripe around the edge to tie the two together. Again we get to the stage where its just about done and bubbles have appeared. heres a photo from the other day showing how close to finished it was (and that there is no debris under the grey). My guess is something is releasing gas thats trapped under the finish somehow, i just wondered if anybody else had had a similar problem and could shed some light on it. Could it be issues with temprature/humidity Quote
Racer X Posted April 14, 2006 Report Posted April 14, 2006 That's why I asked about the underlayment. I figured something might be gassing off. Quote
warped Posted April 14, 2006 Report Posted April 14, 2006 Interesting.... I had something that looked similar when using a metallic grey color (Duplicolor). but I noticed mine when I sprayed the 3rd coat. Some other "odd" things happened with one of the cans I used, like a slightly different color. with less or no "flake" to it. There was something odd about that can of paint! It also appeared to be used when I opened it! Did you use rattle cans? Quote
WezV Posted April 14, 2006 Author Report Posted April 14, 2006 The green wasnt from a can but the grey was. Im at a loss really but at least nobody jumped in and said the wood must be contaminated with something Quote
al heeley Posted April 14, 2006 Report Posted April 14, 2006 I think if the wood was contaminated you'd have seen problems before the final coat. There must be some chemical incompatibility with the metallic and the lacquer layers. Sorry to see, otherwise stunning finish. Quote
