I'm the proud new owner of a 1974 Grumman Sportboat. It's in excellent condition except for some heavy oxidation. I need to remove the oxidation so I can paint the boat for this coming season. Does anyone have experience using Alumiprep 33 to remove oxidation? I'm curious how messy of a process it is. I would like to do this project inside my garage, but I understand that within 2 - 5 minutes of being applied, the Alumiprep needs to be rinsed off. Does this mean a full spraying with a hose, or can the Alumiprep be removed with a wet rag?
Sanding the oxidation off is the other option, but it kills me to scratch the boat up so badly with 80 girt sand paper. I know the scratches will help hold paint, but I plan to use a self-etching primer which should adhere well without all of the scratches.
Thanks in advance for any information or advice.
