Hi Mike, 

With galvanizing, two guys carry the bare frame into the shop, but four to 
six are needed to carry it out after it's been coated. 

Powder coating is durable and looks lovely, will flow and smooth things out. 
But it's difficult to repair if anything ever needs welding. It also can be 
hard to get coverage in tight corners.... you know, the places most prone to 
rust. Sometimes fatigue damage or cracks can be hidden by powdercoat, too, so 
most racers won't use it on frame or suspension parts. 

A simple rattle can spray of paint might be the easiest.  In fact, that's 
probably the closest to the original factory finish on frame and suspension 
parts. 

I usually use "engine paint" on suspension parts, for it's grease, oil and 
heat resistance. My cars frame is coated with POR15 now, tough stuff but I'm 
not 
sure if I'd use it again. It will be a bugger to get off, if it ever needs 
stripping.  

You could have it sprayed with epoxy if you want something a bit more durable 
and still a nice finish. 

Or even a good "marine" grade paint put on with a brush or roller will 
usually do quite well. But, for a nice new frame, you might want a higher 
quality 
finish. 

The inside of the frame on my TR4 is getting Waxoyl, particularly after I 
found the orignal factory applied coating of the stuff had kept a lot of the 
handbrake parts looking like new underneath, after all these years.

Due to take delivery of a new chassis next week for my TR5

What's the best finish for the chassis powdercoating, galvinising or coach
paint.
