You have to look at it this way. The material has already cracked from age (in the sun) and only getting older. Why would we expect no more cracks just because we fixed the first ones? A good job will hold up. But new cracks could possibly develope. You have to consider condition of wheel to start with. There are wheels I wouldn't bother with. Consider use as well. Some restorations rarely get driven or see the sun and others go right back to running around or sitting out. Kits are hokus pocus sold by one stop restoration shops, usually for more money. Research the best individual products and retain total control of the quality in materials. Eastwood doesn't make the stuff they sell.
