Anyone Use Eastwood Diamond Clear

Anyone have any experience with Eastwood's Diamond Clear? If so, how did it hold up?

The website states it should only be used on painted parts. I'm wanting to use it on the 3rd member from my rear axle. I'd like to paint over the unpainted bolts at the pinion area. I'm wondering if this would work out ok or if it would be a bad idea. Any opinions?
 
I used Diamond Clear extensively on a '66 fastback I just finished restoring. The Eastwood disclaimer is correct: you really don't want to put just the clear over bare metal. I did this on several parts, and most of them are beginning to rust again. Areas that were painted and then clearcoated are holding up fine. Keep in mind that this car has sat inside and out of the elements for the last year or so--I'd hate to see how Diamond Clear holds up on bare metal parts on a daily driver!
 
I think you'd have some major adhesion problems unless you prepped the nuts and bolts by sanding or beadblasting.

I would not do it.
 
use a product from POR-15 called glisten pc. i've used it on numerous items & even put it in a spraygun & shot my aluminum intake before installing. had excellent results every time.
 
Thanks for the responses. I'll come up with something different to do. I really like the look of the unpainted bolts but they will just rust since they are only phosphate coated. I suppose I'll paint them red oxide with the rest and clear the whole thing.
 
I tried Diamond Clear once on painted parts and hated it so much that I threw two brand new cans away. It had a very noticeable yellowish tint and was flaking off within a day. I only use Krylon clear now and never have had any problems with that. I don't know if I had a bad mix, but I'll never order it again.
 
Another data point. I used Diamond Clear for bare metal on polished aluminum wheels per the directions. It started faintly yellow, then darkened, and then cracked. I'll never use it again.
 
I've done it with good results. Just make sure the part is clean of oil and grease, including anything from your hands.
 
I know this doesnt help with the original question, but try Sharkhide on aluminum. They have their own site, but Eastwood is a reseller as well.
