My newer model vehicle has a filter system as part of the cooling system. Can I still use either the All-Weather Seal or the Ceramic Seal?
Yes, you can use either of the Irontite Sealant products, however, you must first bypass the filter. In the case of Ceramic Seal, after you have run the Ceramic Seal treatment and removed the product from your cooling system you can remove the filter bypass and run normally. Once the Ceramic Seal has cured in the cooling system it will not re-liquify and as such it will not clog the filter. During the treatment period of either product you must bypass the filter. Since All-Weather Seal is meant to be left in the cooling system, as long as the All-Weather Seal product is flowing in your cooling system the filter bypass must remain.
