Any suggestions on how to treat welded areas on the inside of structures that cannot be reached with tooling? I just installed a rear valance portion butt welding it to existing steel. Of course I was able to grind down and epoxy the outside but the inside has to remain as-welded with charred epoxy, smoke residue etc., there is probably some surface rust on the inside of the original steel also.
I can get in there thru holes and gaps with an extension tube on a spray can and was thinking of just hosing it down with fluid film after the project is done. Is this a valid way or are there other products that I can use.
