don't know exactly why you want to apply it but if it is for mold prevention I kept having to chlorox my cedar siding and my neighbor recommended wet and forget which he got at Sam's or costco. took mold off with chlorox, then sprayed W&F. worked great, just spray it every six months-year and no more mold. don't know if it will eat up EPDM however.
much easier/cheaper than the referenced product.
