Hi Rich,

Thanks for your reply. Just a few questions on some of your 
comments...

Yes, I'm definitely going to use thicker steel when replacing the 
bottom plate of the front crossmember.

Would you have any pictures of this warped frame? Or any more info? 
Such as was the frame structurally sound before dipping? Where did it 
warp, and how badly? How long was the frame submerged in the bath 
for? This is the first frame I've heard of that actually warped, so 
I'd appreciate any info you have on it.

I'd love a pearce frame, but just can't buy it at the moment. But, I 
calculate a huge saving going my route. The galvanising will cost 
about $150, sandblasting and repairs about $350, powdercoating 
another $400 or so. Acid dipping I'm not sure of the cost yet... 
Anyway, it will be significantly lower I expect than buying and 
shipping and importing a stainless frame...

If you don't advise the galvanising process, what would you recommend 
for treating loose epoxy inside the rear crossmember and shocktowers 
where sandblasting could not reach. Then, how would you re-protect 
this area?

Thanks for your advice and good luck wishes! Hopefully it'll all go 
smoothly...

BTW, I do have a full unopened tin of POR-15 gathering dust in my 
garage. I could prime the frame with this, and powdercoat over it. 
How durable would you expect this finish to be? I just don't want to 
go to all this trouble to see rust re-appearing in 4 or 5 years... 
And, I want to make sure that the frame has excellent protection in 
the areas you can see easily, and more importantly, in the areas you 
can't see...

Best wishes,
John
