In that case I will restate my inquiry.
I am aware of the conventional corrosion protection regarding alu. The top surfaces have been look after. I am looking for a product that will protect the "bottom" of an alu trailer. It should be able to seep into, as well as creep in-between pieces of alu that have been riveted. (HL) I will not take the trailer apart to get at the crevices. Either spray or brush on will be a good solution The trailer is built and conventional alu protection on bottom of the trailer can not be used. I hope this is more precise Regards Udo "HL Falbaum" wrote in message ... Actually, the poster covers the question--stating there is no "shortcut" to stabilizing the corrosion. It "hides" in crevices and comes out later. The "glider deserves it" refers to the protection an intact trailer bottom affords a glider. Hartley Falbaum "Udo Rumpf" wrote in message .. . At last some one read the post. In an attempt to be helpful one keys in on a few words. Udo I believe the original post was about the bottom of the trailer instead of the glider. Larry " wrote in message : I would only add two things to the above response. I would use an etching solution such as Alumiprep 33 or Turco with the ScotchBrite, rinse, then coat with Alodine, rinse and prime with a Zinc Chromate paint before topcoating with a two part polyurethane. It's a lot of work but your glider deserves it. As for the shortcut solution, there are coatings which would protect the surface but (at least for aluminium) I haven't seen anything that would stabilize the corrosion that is already there. |
