[T3] Undervoat question

[David Sanderson]

Hi Bob and Keith

Thanks for the comments - even though it seems that I cannot spell  
undercoat. I have stripped all the undercoat away and was planning on  
first epoxy primer and then the single stage paint that they mixed for  
me. That's the paint I used for al the underside of the shell itself.  
I had not thought of using the base-clear combination. Bob, do you  
think the single stage would be enough or do you prefer, would you  
recommend, going to the base-clear combination?

Dave
