Guitarfrenzy Posted July 14, 2003 Report Share Posted July 14, 2003 I was looking at my finish job.. and noticed small dips all over it.. small.. but still dips just the same... then I started searching the web for information on painting flaws.. and looks like I got orange peel.. the only thing I'm wondering is.. what caused it to happen... does all spray can paints do this or am I totally doing something wrong.. maybe I had too much air movement..? not quite sure.. but I don't want to do that again.. I read that I'd have to sand down quite a bit.. I just hope it's not past the clear coat.. if it is.. I might have to redo the whole thing.. Yikes...

Guitarfrenzy Posted July 14, 2003 Author Report Share Posted July 14, 2003 I've been reading more about this and from what I can tell.. It was way too hot for me to be painting... the lacquer dryed before it hit the wood.. Here is some information I found on the subject off the internet... Orange Peel Identification Uneven surface formation, texture like skin of an orange Cause: • Improper spraying pressure/technique or application temperatures • Improper flash or recoat times between coats • Extreme shop temperatures (When air temperature is too high, droplets lose more solvent and dry out before they can flow out and level.) • Use of improper reducer/thinner (Fast evaporating solvents cause the atomized droplets to dry before they reach the surface.) • Materials not mixed correctly Prevention: • Use proper gun adjustments, techniques and recommended pressures • Schedule paint jobs to avoid extreme temperature/humidity conditions • Allow proper drytimes for undercoats/topcoats per manufacturer’s recommendations • Use recommended thinners per manufacturer’s instructions • Follow paint mixing instructions carefully per manufacturer’s recommendations Repair Process: • Sand and buff using a mild polishing compound for enamel, rubbing compound for lacquer • In extreme conditions, sand to smooth surface and respray topcoat Quote Link to comment Share on other sites More sharing options...
krazyderek Posted July 14, 2003 Report Share Posted July 14, 2003 yet another reason i'm leaning towards tsl's roller method... sprays are to bitchy if you're just starting out IMO, i hope you get everything figured out.. but couldn't you just put on some more clear coats so you'll have lots there to sand with no worries? i mean.... if you put on like 20 more coats of clear then all you have to do is use one of those sanding blocks to get a flat top and bottom... like... bring the dips up with the coats and sand down to the lowest point..? ok i'm tired... sorry if that doesn't make sense...

woodfixer Posted July 14, 2003 Report Share Posted July 14, 2003 I think since you were using a spray can and not mixing that you had something on the surface which the spray didn't agree with.Chemical reaction.Resand surface blow off clean and spray a very light mist ,repeat. Then do your wet coats.Do not introduce any chemicals from rags etc. Quote Link to comment Share on other sites More sharing options...
Guitarfrenzy Posted July 14, 2003 Author Report Share Posted July 14, 2003 Yeah.. I'm thinking I mixed Acrylic Lacquer and Nitrocellulose Lacquer but the high temperature didn't help much... also.. I was in an environment where there was too much air movement... But last night I got lucky.. thank god I put 14 coats of clear on it... I did what Brian, and Krazyderek suggested... I started sanding.. thinking that I'd have to spray more clear coats over it..... So I began wet sanding with 400 grit.. simply because I tried 800 grit and it still showed... I sanded it until.. all the surface became dull... cause I found that if there was any shiny spots.. they'd show up later no matter what finer grit i used... ... so I got a nice dull finish... then started with 600 grit.. wet sanded with it a while... then 800 grit.. and finally 1000 grit.. then I used a 3m polishing compound.. and applied it and used a rag to swirl it on ... and to my suprise... It looked great... I mean really good.. lol... only thing I see is lightly scratches in the finish... The 3m compound I used said it was for taking the scratches out of 1500 grit and lighter... so I'm thinking I should have used even lighter grit like 1200 and 1500 to get a better finish.. any suggestions? I'm gonna hook a attachment to the drill today and sand it that way... maybe it will do better... Matt Quote Link to comment Share on other sites More sharing options...
