Manufacturer JENOLITE. ONLY USE IN WELL VENTILATED AREAS: Remove all traces of oil and grease with suitable degreaser. Remove old paint and loose rust with steel wool or wire brush. Shake the can well before use so that the agitator ball can be heard rattling.
To the best of my understanding, Jenolite make only top quality products. This Etch Primer is amongst that group, as it sticks to every metal, [both Ferrous and Non-Ferrous Metals], which I have applied it to, making it invaluable to me.
Buy it and try it-I believe you will be pleased with the results.
