marine clean you say... no i washed down the surface with warm soapy water then thoroughly dried it with a towel and heat gun. my first thought was that there may be some water catching in the little scratches from sanding.

oh and its always inside too.

Interesting reading here..

"Keyphos is a phosphate/resin system applied by dip, brush or spray, it comes in black or clear, although all the race teams over here use the black. It has to be stoved after application."

I'd be using the products por15 recommend... soapy water won't remove any oilly contaminants at all, if you don't have the marine clean at least clean the shell with some prepsol or metho.

Picture of my shell in metal ready for you (sorry not the best picture):

Ohh.....

I will just have to make sure i get it offf really good - plenty of Prepsol

_________________

I use emerphos (c) on bare metal repairs as it converts any rust to summin else and then i hit it with regular areosol grey primer till i am ready to properly paint then it is a simple scuff with a scotchbrite to remove that primer. Not really teh cheapest way to do it but it gets the job done till i have time to spray the whole car

I would use a rust convertor that has a high content of Phosphoric acid, This will leave a phosphate coating, After looking at the photos I think Hanras body shell has been coated with a product that has a high content of Phosphoric acid, Do not let the word Acid be a concern in this case, As it is not a strong Acid, it is in a lot of soft drinks

But all the same...use rubber gloves, eye protection and a respirator if you have one

yep safety first

what would be regarded as a high level??

Yes rubber gloves recommended -i have been using a product called something like rust dissolver - it has phosphoric acid in it. i wasnt using gloves - i figured its not hurting me so what.. washed my hands and thought they were smoother i think it may have thinned my finger tips
goggles/glasses only common sense

Yes I Agree, Sorry I was thinking more about people being concerned of the corosive effect of an acid on their car

Like Coca Cola Highest content of Phosphoric acid of all the commercial brands.

When buying rust converters I look at the labels and buy the one with the highest percentage. In fact the last time I bought some the one with the highest concentration was a lot cheaper than a well known brand that was the weakest - go figure. Avoid the ones that don't state what is in them - means the amount is below the poisons regulations minimum level that requires the appropriate warning and first aid labels.

Still looking for a brand I used a number of years ago that stated on the label (and was evident in use) that it left a "plastic" film to protect and seal the surface and provided a base for painting over - worked well and you could see it was done as the film left a shine on the metal.

Wombat,
That one was probably Permatex in the white bottle with orange cap.
It is still about but is Loctite branded now.
It is good stuff, best I've used.

Another good one like this was Selleys, but it got taken off the market I think.

Thanks John...its just that the range of products and the concentrations vary...fer instance, my bottle of DE.OX.IT is 25% Phosphoric...nasty stuff
