glennonrp there are 3 different Mr. Surfacers. 500, 1000, and 1200. 500 is the thickest of the trio with 1200 being the thinnest. 500 can fill in minor gaps, scratches, pin holes, resin air bubbles, and even many narrow seams. The pics of the 500 your seeing in previous post are directly after the product has been applied. Given 10-15 minutes and it will dry but also shrink as it evaporates. Eventually a second application sometimes will be applied to assure good coverage. I don't think your doing anything wrong. You just need to apply it one, perhaps two more times to get the results your looking for. Hope this helps.
