Clearcoat
 

I am painting a 106" wingspan Extra IMAC airplane. I am posting on the Jet forum because I know you guys paint. Very few IMAC flyers build and almost none paint except for cowls and wheel pants. I used PPG K36 prima, and Omni MBC basecoat. In the past I used PPG DAU75 Delclear as my clearcoat. I also used Omni MC161 clear. I am interested in keeping the plane at a reasonable weight.
I am wondering what you guys are using for a Clearcoat nowdays?
Thanks,
Jim DeYoung

MC161 baby! And lots of elbow grease. I wetsand upto 2000 grit and then use a 6" buffing wheel with 3M Perfect it!
Works for me.

I use PPG 2021 with the DFX11 accelerator. i thin about 3 times what they recommend. the faster hardener will prevent stuff/dust from setting in and allows to dry faster since I thin it more. I thin it like this so that I can put it on thin, have it flow, no orange peel. i also keep a small touch-up gun ready to go with retarder, so if you get it too thin and it does not look wet enough or you get some overspray, the retarder sprayed with a light coat will help wet and get it to flow, but it dries quick, to typically no runs, unless you over-do it. If you do it right, it will look like it was buffed.

HI, they have not sold MC 161 for a couple of years now, I use Omni MC270, it is very thin, but you can easily still add 25% reducer. I use a Satta gun, the gun makes all the difference.

MC260 and 270 is not available anymore in many states, the new VOC compliant Omni clear is MC262. Anyway, check out this thread I did with my firebird, it talks about clear coating, and all stages of prep through polishing. Hope it helps. I cannot recommend reducing paints beyond what the manufacture recommends, I don't agree with it, but to each their own.

MC 770 is the new VOC compliant clear, here in Canada.
You can still buy MC270 in some states in the USA
