Oops! I made a mistake. I have not clear coated the test sample yet, as I stated above. I have made another test patch. I have painted it with the Fusion Yellow and I am going to let it set for 24 hours. Then I am going to clear coat and let set another 24 hours. Then I'll test for fuel. I will take this patch to the field with me and hold it behind the exhaust.

On the 1st patch (the patch mentioned in prev. post) that had not been clear coated I took a swab and dipped it into acetone and rubbed the patch. It did begin to smear after a couple of swipes. The pieces of UltraCote and UltraCote adhesive striping are stuck real good.

Then I poured 10% fuel on the patch and let it sit about 5 hours. Took paper towel and wiped up the fuel and no yellow on the towel. It did not affect the paint nor did it penetrate the paint and covering.

I am anxious to clear coat and test. However, I am told by some who have some expereince that you need to let everything cure for about a week before you try anything.
