With the Texas temperatures in a constant state of flux I have been picky about my days I choose to go flying lately. On some of the cooler days (like yesterday, the 13th) I have been polishing on the upper surfaces of the 170s flaps and ailerons. They are in need of some serious work after the paint work done of them. The cleaner used to prep the lower surfaces bled through the paper and left some residue that is proving to be stubborn! I have been polishing with Nuvite F7 (from Perfect Polish) and it is working quite well. Hope to have made good progress on polishing out the wings this month. So the last time I flew was on the 6th. Should be able to do some flying later this week as the weather is looking good.
