Weld repairs - before or after media blasting??

[camerashy]

The Datsun is getting walnut blasted next month, should I do the welding before or after it's been blasted?

I'm picking up the generator on friday so I could in theory crack on over the weekend and likely finish ALL the welding that needs doing - there really isn't much, just lots of tiny holes to fill, or is it more advisable to wait until after the blasting is done and then weld? I can't really see it making a difference, just wondering if anyone has any suggestions/past experience on the matter.

Cheers

I`m finishing all the metalwork on the Kadett before it goes for blasting, on the basis that it can then go straight in to prep and paint

Two methods and only you can choose what is best for yourself.
I'm going to have my Sprite shell blasted and zinc primed BEFORE I restore. That way metal that looks sound but in fact is paper thin due to internal corrosion or pin holes will be obvious. I've seen people do it after thinking every bit or rust and rot was removed only to have holes appear when blasted so they have to take the vehicle back home and start welding again.

I take it just the shells are used for walnut blasting then Using the nuts would be a wanton waste. I wonder how many walnut wips have to be eaten to blast the average car

Would get it blasted first then you can see any hidden nasties. Better than doing the welding. Having it blasted then finding a load more work you never though was there.

Very much hoping you don't have 1% of the surprises that happened when the last one went for blasting

Good luck,
