Have an aluminum trim on some rear fender wells of an all out custom body, the TIG weld are text book perfect. Need to be smooth and clean looking. Only problem is, the aluminum is being left in a polished state NO PAINT! I was looking at several things and tried a few; different metal "caulks" from Lowe's etc.

I saw the Chem Weld products and some similar stuff but the "dry color" isn't the greatest match for polished aluminum. It could be clear coated if needed I suppose (for UV protection)
