When I was working on my canopy frame to make it fit, the powder coating cracked and flaked off showing bare metal with a little rust. Made me not a big believer in powder coating, but maybe its OK with the right prep. When I hear people talking about the greatness of powder coating it always brings back memories! This was in about 2003 because my 7A has been flying since 2004. To be honest I scraped off the loose coating, touched it up with a spray can, and have pretty much forgotten about it. Wow! Has it been 10 years? Thanks, Matt for bringing this to Van's attention. I enjoy following your building progress. Dan Hopper N766DH In a message dated 7/13/2014 7:03:07 P.M.

Sound like not much has changed with Van's powder coating supplier.

While stripping, I have noticed a couple of things regarding factory powder coating. Perhaps the most disturbing was the high build up rust under parts in certain areas, primarily the ones made from the 4130 plate (see attached pictures). This will eventually cause the powder to flake off. > >The other issue is the distinct lack of surface prep on all steel parts! On every single steel part that I have stripped, there is no surface preparation such as scuffing and/or phosphating. All of my steel parts will be undergoing these steps prior to powder coating for the absolute best possible protection from future rust break through. Additionally, the adhesion of the powder coat is significantly better with these additional surface preparations. The cost differential is minimal, since high-end coaters usually do these steps by default. > >Many builders faced with changing the color of their steel parts will simply choose to paint or powder coat over the top of the factory powder coating. This will eventually lead to a less-than-satisfactory result for the reasons outlined above. > >FYI. > >- >Matt Dralle - Matt Dralle RV-8 #82880 N998RV "Ruby Vixen" http://www.mattsrv8.com - Matt's Complete RV-8 Construction Log http://www.mattsrv8.com/Mishap - Landing Mishap Rebuild Log http://www.youtube.com/MattsRV8 - Matt's RV-8 HDTV YouTube Channel Status: 172+ Hours TTSN - Rebuilding Fuselage After Landing Mishap...
