Rocket, yes painted black would be nice I only took my bike out a few time and its painted with a heat paint It seemed to be fine .
But I was told on a hot day being stuck in traffic my paint might blister being so close to the exhaust, and being wood under fiberglass I really didn't want to take that chance of a fire

. So I put alluminum on the back and put some vents on the bottom and it was fine.
Then I decided to change it a little by putting that vent on the side and realized that my back was all covered in alluminum all's I need to do is to weld it and put my sides on then weld the side take out the scews fill the holes polish it all up and I have one made out of alluminum sounds easy

and I could do the same way out of other metals so I think one day I could make these bottom pieces for other captans one day and this way I could make the two types.
And when I do make one out of alluminum I will do another one and get it chromed and see what look I like the best.
