I had the cast aluminum binnacle components on my Crealock 34 stripped, prepped and painted with Awlgrip around 1-1/2 years ago. The paint is bubbling horribly at this point.
It is clear that the applicator botched the Awlgrip job as the finish never truly cured. However, it is also clear that despite abrading the surfaces with coated and non-woven abrasives and grit blasting with a fine glass media we were unsuccessful in ferreting out all of the previous corrosion.
Two questions:
1. Has anyone had experience successfully prepping previously corroded cast aluminum? How did you do it?
2. Does anyone have any insight into the relative merits of powder coating vs Awlgrip or other "wet" coatings?
Thanks.
