Looking for UV-Protected, Durable Powder Coatings

Question:

What powder coat offers UV protection, excellent durability, is suitable for an automobile frame and will cure under 300°F or lower? I have the inside of my frame rails coated with a liquid paint product called Rust Bullet, which will fail at temps above 325°F. It would also need to be a semi gloss (60-75%) and available in black.  

What filler would work to fill small pitting holes before coating? Thanks for any information you can provide. C. C.

Answer:

Another "Car Nut" question!

You want to use Lab Metal by Alvin Products, Inc for your filler, since it is easy to apply, is conductive, can be sanded smooth and can withstand the heat necessary to cure the powder coating. They can be contacted through www.pfonline.com/suppliers.html.

When you send your frame out to be powder coated ask for a low-cure TGIC powder coating. These can be cured at 280–300°F, although for a longer amount of time and are readily available in semi-gloss black. This powder is very UV stable and very durable for your use.
