I used Smooth Prime put on with a roller when I repainted mine and I really liked it. Only comment I have on it is to make sure you vacuum or blow off the surface after sanding before you put on another coat of primer or the final paint. You can get some small bubbles in it and when you sand off the top of the bubbles you wind up with pin holes. Not a lot of them and no problem to fill them, but if you don't blow off or vacuum the surface they fill with the sanding dust and you don't know they are there until you see them after spraying your final coat. I filled the pin holes with icing and a quick sand in no time at all.

It seems a bit expensive now but it wasn't cheap back then either. I don't recall how much it took but certainly not the three gallon it suggest in the ad, maybe a gallon and a quart. It is water based and I put it on a bit at a time with a 4 inch foam roll as I finished different areas of the plane. I covered it with cheap auto paint ($40 a gallon in early 2000) and it still looks like the day it was painted. Paint was never buffed out and I still have two spots on the left wing that have been in primer since 2004 where I cut in to the wing to fix a fuel leak. Nobody every notices the primer spots and I've just never bothered to paint them. The trick to eliminating fill is to get the foam right, get a good glass lay up, then cover with "deck cloth" for minimum fill. If you look "real close" you can see one of the primer spots in the photo. https://dl.dropboxusercontent.com/u/32133949/024_24.JPG Larry Flesner _______________________________________________ Search the KRnet Archives at http://tugantek.com/archmailv2-kr/search.
