 Posted: Sat Nov 28, 2009 7:15 pm Post subject: QB Corrosion - Heads Up |
 |
|
This is intended for those listers who recently received their QB’s.
I’ve had mine for nearly 2 months and have now started seeing filiform corrosion forming on some of the areas where wash primer was not properly applied. If you look at the surface of your aluminum, you might notice it does not have a uniform color. The darker patches are where the primer was not properly applied and the corrosion is occurring only in these darker areas.
From this point forward, I’m going to scotchbrite out the corrosion and chase it with rattle can primer.
If you’ve got a recent kit, keep your eyes peeled and take a good hard look in the darker tinted areas. The corrosion I am seeing is white and each runner is around 1/8” long.

Welcome back to work everyone. J
After closer inspection yesterday I found more than a dozen areas of filiform intruding on the interior surfaces.
I’m thinking I’ll try and scrub out the corrosion then treat those areas with an alodine pen. After that I’ll go ahead and shoot the entire interior with the same self etching primer I used in the tail (Variprime).
Have any of you primed over the top of Vans wash primer? If so, what did you do to prep the area and how well did your primer adhere?
Thanks for the help,
Phil

Place a call to Vans support (if you haven't already) they will give you their version of what to do, if nothing else they need to be aware of their priming issues.
My concern is that a few years back I grabbed a rusted fence and completely removed everything, I applied a few different primers (rust oleum, DTM wask primer, etc) than painted over it with a exterior paint. 1 year later I discovered rust was developing again. All I can think of is that I didn't get it all- although I sure thought I had everything covered.. My point is you probably need to pull some panels out and see if there is anything else "hidden" if you don’t you may very well find some more surprises later that will stread back to what you already did, no matter how well you do it now..

Talked with Scott (at) Vans and he suggested the process below.
Just scrub out the corrosion, alodine, then prime.
So that's the plan.... It'll probably be next weekend before I can get
around to it.
