A few "hard learn" experiences
Sanding will tightly bond Polyglow, mold release, old wax (anything on the surface) quite tightly into the fibreglass. After sanding, you need to use the appropriate solvent to wash it away. Wiping will not do it - and liquids that are not solvents to ALL materials you sanded will not do it either. You also need to use lots of rags/paper towels as you simply spread it around after about 5 seconds of wiping. This is hard experience from people who do this for a living. Second tip is that if you are going to use a product like Interprotect, use the recommended solvent to remove the sanded in crud and prepare the surface. Don't substitute with acetone etc if a specific product is recommended. Many times, the solvent is a blend that drastically affects adhesion. This is not where you want to save $5 by taking a chance that the giver of "free advice" actually knows the chemical composition of what he's talking about. Why take the chance? It's all in the prep and using the recommended products exactly as the manufacturer recommends - that's the difference between permanent and having to do it again... Chris
