Does anyone know what the Vmax side covers are made of ? I sent them to Jet-Hot to be coated and they told me they were aluminum and were too thin to be coated with their product. They said that they had to get them really hot to cure the coating and they might melt. I saw a listing somewhere that said they were tin and if so, they should be able to withstand the heat. Whaddaya think?:ummm:
