for Angier:

I just completed a "hanger" paint job on a L-IVP using Randolph polyurethane (see aircraft spruce catalog).  This was a 2 (heavy) coat application with no clear coat.   I am hoping the polyurethane might avoid the fine cracks around the pressurized door that some of the clear-coat materials show.  Time will tell.

Some thoughts:  This material is quite toxic and required positive air breathing equipment.   Certain colors, such as yellow and red, are very translucent and require a perfect, no blemish, undercoat;   altho the darker paints cover quite well.    Also, polyurethane is a very hard material when cured.  Sanding out runs and then using a buffing machine to apply rubbing compound, is a lot of work. The job took 3 times as long as I originally anticipated because I didnt factor in weather changes.   At last count, there were 37 pieces that had to be painted individually and I also had to build a rotisserie to handle the wings.  Adding different colors is also very time consuming.  I estimate that it took me over 6 months to complete the job.

I mentioned once before, that I would never paint an airplane again.  I  suggest flying in prime to work out all the bugs, then having a professional do the paint.

Good luck    Bill Hogarty
