Hi
Hoping someone can help with alu frame restoration advice.
Recently took a 7005 alu MTB frame to a powder coaters in Eastleigh. The frame was originally finished with a translucent paint over a silver/chrome effect base. Once stripped it appears the aluminium had oxidised under the silver base coat in one or two places. In doing so it must have lifted the paint slightly as it wasn’t visible through the original paint.
I expected some oxidisation as there was an amount elsewhere so my expectation was the raised oxidisation could just be sanded down and then powder coated.
Unfortunately the powder coaters were unable/unwilling to do this and instead layered additional powder coat over the frame in an attempt to hide the oxidisation as best as possible. As a result the powder coat has run in a few places and isn’t that great but on the plus side it’s bloody thick! At the time though not 100% happy with the result it would do for what I wanted the bike for.
However the more I look at it the less I’m happy with it and if I build it up I know it’s going to constantly annoy me.
So am I right in my assumption that if stripped again I can just sand that raised oxidisation down so it’s smooth and level with the tubing and get powder coated again? Or am I best just sticking with the result I have as it’s the best I can expect?
Cheers
