Flash Rust

[Bitsa (Ralph Wright - RIP)]

Hi Guys,
When I got the bike I can not remember inside being so rusty before it was repainted.When I collected it the sprayer warned me of the rust inside didn't take much notice just removed what I could and got on with it.Read some where when its been resprayed and put in an oven to rapid dry can cause this as the heat drys the inside out causing flash rusting.Is this true?
Can anyone help as I am about to get another done and its rust free inside and if this is the case I will tell him to let it dry Naturally.
Cheers

Hi,
     Two biggest causes of "flash" rusting are the use of chemical cleaners and bead-blasting,these surfaces need to be primed almost within the hour to prevent a sudden rust attack----Ken

Cheers Ken,
Thanks for your answer but my main concern is the interior.I did spray it full of something I cant remember same thing as my exhaust which has preserved it very well for 3 years now but what I am asking is does ovens create flash rust inside the tank/

Hi Bitsa,
               A lifetime in engineering says no to flash rust through that level of heat on its own, but what effect that heat has on residues left on metal surfaces is anyone's guess, a tank is one thing I have never thought of "stoving" due to the thin-ness of metal and welded seams---ken

Cheers Ken Lets see what happens when I get it back.

Hi Guys.
Well the natural drying process seemed to work got it back today and still crystal clear of rust.Good job well happy now.The white bit you can see is a feather.

Hi Bitsa,
            Great about the interior, and a good looking paint job as well---Ken

Thanks guys,
Mick used the French guy paid 400 euros which I think was not a bad price as there was 3 dents to fill as well.I gave him a side panel for him to match and I do not have a lot to say praising the French around here but he is bloody good he is a biker Harley unfortunately.The photo is how it started out.

Did you fit the fuel cap I found it a real bastered I was crapping my self working that close to fresh paint.

[Bitsa (Ralph Wright - RIP)]

Mick.
Yes to all done it many a time when I did insurance repairs back in the 70s.Have to say though today had shit loads of rags around it as with respraying every thing is alot thicker than it was had to clean excessive paint off to get the cap and washers to refit same with the lock part.Badges no problem the clips fitted nice and tight.

I had to clean the paint off for the push button on the gold tank.
Rather stupidly I took the paint of the wrong side and had to touch it in.

Mick,
Been there done that.Thats how we learn mate.If the chrome covers it thats the side you take the paint off.Like I said easy done we are not the first and we will not be the last.I think its called experience.
