I have been using a weld-thru primer for patch panels and rust repair and recently notice that I am having some rust under welds at seams, even though weld-thru primer was used.
Are there any tricks or other types of products that I should use under welds.
Note: that this area had not been in the weather outside at all, always protected.:grumpy::grumpy:
