So I painted my car. Got some orange peel, thought I'd see if anyone had ideas for getting rid of/minimizing it.
After painting: After sanding with 1000 grit. The lighter areas are where I sanded, the darker areas are the lower points of the orange peel: Option 1: I'm thinking I need to go to 800 grit, then 1000, 1500, 2000, then polish. Before I do I thought I'd see if anyone else thinks this is a good idea based on what they may have done. Option 2: I can re-paint it. I'm thinking I will sand with 400 grit to rough up the surface and then re-spray. Option 3: I can polish it more, but the orange peel is still noticeable on the smaller pieces I've tried. I used a Torq X polisher, white pad, Chemical Guys V32 polish. I thought it might get smoother as I polished it with finer and finer pads/compounds, but I don't want to burn thru the paint. I put 3 coats of paint on. |

I have been told that compressed air can be very hot and that might be yet another issue I need to address. I'm going to run the compressor and some air tools for 20-30 minutes and see how hot the air gets.
I'm thinking I will place the first hose in a bucket of ice and see what that does. Air coolers are available but they are not cheap. |

Air coolers are available but they are not cheap. Your coats are not laying wet enough.. Simple as that.. Your chasing problems that just simply a wild goose chase. Not trying to be difficult and note I am not expert but have used my sanborn 80 gallon air compressor with a simple air dryer and painted about 5 cars with it over about 10 year period. I have a simple sata hvlp spray gun that is 10 years old. Attached is the results of my job. I would really suggest yoy spray out some parts that may either not be seen or a fender from the junk yard to get a feel for it.. |

I would really suggest yoy spray out some parts that may either not be seen or a fender from the junk yard to get a feel for it.. (IMG:style_emoticons/default/agree.gif) done heaps of DIY garage resprays,don't spray dry as you will need to sand between coats for that reason and you shouldn't have to unless the basecoat has been on too long,dry spray feels like sandpaper and shows up really dull,if you are painting single stage expect to have orange peel....that's normal. If you put orange peel over orange peel you still have the same,way this paint is. Lay down the right amount of basecoat to paint makers specs for reducer and you will be fine,keep the gun moving the right distance away and stop and look what you have done and adjust what you are doing as required. Reason for chiming in as I'am currently respraying our GTI golf,I have no spray tent,or flash system of any kind,just gear I have used for years that works like Ben said and getting a great "off the gun" finish,spray @ the coolest part of the day and reduce moisture in the system as much as possibly with a water separator. Good luck ok ?. |
