(Need to apply beeswax to the foundations.)
Yes Sir, Perhaps beeswax will seal in the asphalt smell. I am assuming these foundations are plastic. You may have already heard of what I am about to suggest. There is a fellow in Florida that melts his old combs in a stainless steel vat each season. He saves this for dipping his plastic foundation in for coating. This practice makes a quick, effective and efficient way to coat his plastic foundation. I have not tried this but it certainly sounds promising. Being you are just getting things into gear you may not have the wax resources to accomplish this, but in the future, this may be worth looking into. I hope this helps you.
