Tamco HH57 Basecoat Hardener

Tamco Basecoats may be mixed conventionally at a ratio of 1 parts color to 1 part HR reducer. However, for added durability, the addition of a hardener is sometimes recommended. Adding a hardener significantly improves adhesion of the basecoat to the clearcoat. For added durability on exterior parts, or to meet certain OEM specifications, you may have to use HH-57 to catalyze Tamco Basecoats.

Another great product.

I found out how well it works when i had to redo a couple parts with and without it. The difference in sanding the intercoat with flake off the parts i used with the hh-57 was very noticeable. I highly recommend adding it to intercoat or other basecoats. My only complaint is it comes in 8 oz bottles only.

We appreciate your positive feedback. Thank you for supporting our small business :)

Great Hardner

HH57 is a great Hardener. Easy to use and a little goes a long way. Only 8 ounces for a whole gallon of paint. Will use it in every paint I get from Tamco. Just another item in their great line of products.
