What is the difference between VHT SP-995 Nu-Cast Aluminum and VHT SP-997 Nu-Cast Iron Engine?
SP-995 Nu-Cast Aluminum duplicates newly cast aluminum as in: new alternators or intake manifolds. SP-998 duplicates the cast gray look of a newly cast Iron Engine. Both are ideal for restoration or making old parts look new. Both products are rated to 290°C and very chemical resistant after heated one time.
