In Looking at your Crankbait , I am inclined to agree with BobP .. I foil a good many baits and I would try one piece cut down to the swelled area , seperate piece for the swelled area and another on the bottom .. Blending them together with your scaling tool.. Also you could cut with your tools a deeper grove around the swelled where it meets the body of the crankbait and hide the seams there .. Just a thought ... Most wrinkles you can rub out with a solid tool and then press your scale in and never know where the seams are except if you use heavy type foil.. I like Venture as Bob P mentioned , a lot thinner and peel and stick .. Big Craft Stores usually carry it ... Give it a try and let us know if you find a better one (or I should say , "one easier to work with") . .Good Luck
