Most of the appliances on my roof do not have any type of sealant over the bolts or mounting plates .<br/><br/>I have read that Foretravel does not use any but worry that a leak may occur that could have been prevented. My ceiling is vinyl so I will not notice a leak till it's way too late.<br/><br/>Any recommendations as to which product to use ? Caulking or tape?<br/><br/>Thanks<br/><br/><br/>
