Before trying to remove the scratches, first find out from Heartland if it can be done. With my 2011 Grand Canyon it says the it is a True Solid Surface so I think I can do it with mine. If you can, here is how I would do it. I would follow the same process as if I was finishing a table top I just finished. For the counter top, sand using no less that #600 to start (depending on how deep the scratches are), then move up to #1200 to 1500. Use water at all times. Wrap the sandpaper around a wood block to keep a flat surface, go in one direction only, make as long a stroke as you can overlap as you go. Then, I would use Pumice (first) then Rottenstone to level and polish. What is Pumice and Rottenstone, they are fine cutting dust used in woodworking to level a table top that was just finished. You can purchase this at woodworking supply stores like Lee Valley. You can use either water to kerosene as the lubricant for the Pumice and Rottenstone. I use kerosene as it is a better lubricant. If the countertop is the same size as in my Grand Canyon, I think it should take about 4 hours depending on how deep the scratches are.
Hope this helps,
