    Every now and then I’ll have an issue with blending Sikken’s Autobase. (Especially Honda Silvers) One problem is sometimes it tends to fog out on me and sometimes it won’t. Sometime is won’t fog out with a coat of blending additive down and sometimes it will. Also another issue I have is on a blend panel Ill have spots show up from the metallic. To me it looks like the metallic gets caught in the orange peel on the blend panel. I think it is from the clear not being sanded completely smooth. I’ve brought the issue to my boss’ attention and he seems to not care and insists it is because it is not wet sanded. Also the other painters I work with don’t seem give me an answer I need other than to tack it off, but sometime it won’t tack off. Has anyone out there ran into this issue before?

    I used to spray sikkens autobase,autobase plus,and now I shoot autowave.I always would put down one coat of blending additive(basefix back in the day) on my blend area.I always used a slower reducer to stop the base from drying in the air before it hits the panel when doing a blend,this can cause mottling or haloing.Also for my blend on my last coat I would add a little more slower reducer.I always found that the flash time was the same whether I used fast or slow reducer in my booth.Not many painters know this but the high performance reducers contain a lot of acetone which makes them slower to flash,I found the lesonal reducers worked better and were more like the old 123 reducers.HTH 😉

    I sprayed autobase for years and the honda silvers, ex. NH-623-M has many varients,if the flip is not right on, you might see the blend.I would always put a coat of basefix down to fill uneven sandscratches (scuff pads)and let me see the blend easier, and slow reducer is the ticket,to keep the metalic wet and letting it lay down. I remember those “spots” caught up in the peel.I used slow even in the winter, in the blending of most metalics.Using Autowave now also.

    Thanks a lot for the input jayson and steve!!!! I generally use slow reducer in all of my metallics but this past week it has been very hot out 95 + and the thought never crossed my mind but Im starting to think that maybe even a slow reducer may have been too fast for the temperature. Im getting way more input from everyone on here than I can get at work!!! I know where to come when I have a issue or question from now on!!!!

    You are welcome,I have sprayed sikkens for well over 23 years and everyday for the last 9,I know the system inside and out 😉 Sikkens also makes an extra slow reducer for hot weather,you can mix it 1:1 with slow or use it straight.You can also reduce autobase plus up to 80%(I mixed it 2:1) this will help in extreme temps.If you have any other questions let me know. :welc to the site by the way

    Try this… Lay down your wetbed of blend additive over entire area. This gives a uniform surface for your basecoat to lay down on. Let flash… Apply color to bodywork area until you have desired coverage. Start your blend,and if silvers are the problem, try adding 666 right into your basecoat. You can add as much as you like but usually you wont need more than 50%… 666 is crystal clear and will not affect the fliptone, as 777 will. This should make the transition more gentle and less visible. Airflow and humidity play a huge factor in waterborne paints, so pay close attention to these. Motteling or haloing is usually caused by several factors and gun control, spray technique and air temp play a major factor, so watch your air pressure, distance,heat in booth, and never force blow the blend area. Tried it several times and the results are outstanding.

    Good advice dude but he is using autobase plus solvent system NOT autowave waterborne system 😉

    Jason is right about the slower reducer. DuPont is the same way……….

    Thanks for the input guys Ill try to slow it down even more next time and see how it works. I hope this is the ticket because Im getting tired of having to battle with this stuff. The good thing is it cooled down this week so the paint booths wont feel like they are on bake when Im spraying!!! :cheer: Ill keep you guys posted on the outcome!!!

    This week was my week to paint again and I had a bumper and quarter repaint plus a door blend on a silver toyota (code 1D0). I did everything you guys told me to do. Put down a coat of blending additive and reduced my base 80% with extra slow reducer. It worked AWESOME looked like a text book blend there was no foggy spots or nothing in the blend panel. You guys were also right on the flash time I didn’t notice any difference in flash times from slow reducer to extra slow. Once again thank you so much for the input!!!!
