filler for rusty top

[sanctuary79]

hi...i am in the process or preping my steel roof (arg!) for a fresh coat of the first primer.

it has some rust spot that i plan to use vactan on and fill too where needs be...

 

What filler should i use and the best practices too would be grand...

 

Thanks

Personaly I would prefer to use a knifing stopper than filler because it doesn't absorb water if the paint gets damaged later, on a sunny day it will set very quickly and is easier to flat. The usual sequence (for me) rust treatment, primer, stopper, flat, re-prime any exposed metal, undercoat.

 

But no doubt others do things differently.

With tea and biccies.

May I suggest the best biccies are Hob-Nobs - - you find that they bind with the irregular pitting in the steelwork better than most others . .

(It is essential that you apply them wet, however!)

But with Hob-Nobs you have that slow-motion moment when the dunked bit breaks off and disappears back into the mug of tea...
