Default Re: Help on an 1993 astro s18b

Here's the two pictures you e-mailed me, I've resized them to 800 pixels wide and placed them into your free gallery here on Marine31Online.com


I'm not familiar with how Astro lays up thier hulls but my guess is this is either,
1. Clear polyester resin over a mylar or metallic flake ontop of a colored or pigmented polyester resin.

Or

2. It's an automotive basecoat/clearcoat paint sprayed over a pigmented gel-coat hull.
My guess is the first option as that would make sense, be a lot more stout and cost a lot less to produce.


Assuming it's option 1...

I think the "color" part of the gel-coat is fine. You've cleared up the surface to see the colored or pigmented and flaked underlying portion and the color diference is either normal from the factory or faded from exposure to sun over time.


Here's the dealio....

You can only "affect" the surface, you cannot affect what's under the surface. So finish buffing out the boat and slap some wax on it and then get out on the water and enjoy!










These look like stress cracks to me, that is the random lines in the surface. You cannot do anything to fix these as they are "in" the clear resin, not "on" the clear resin.





My guess is these results look a million times better than from where you started so just keep on compounding followed by polishing and then seal her up.

How about a far shot of the boat showing the entire boat from the side and front?
