Right peeps,

had my tank de-rusted form these guys and it came back yesterday.

now I am sealing it tomorrow night and then letting it cure for 48 hours.

the question is, they put a phosphor coating on the steel (assuming its to stop the rot) and the guy said to paint it asap. I need to put filler on the tank to get the proper profiles etc.

now the question (get on with it dewpy!)

1) do i apply filler over the phosphor coating

2) sand (ie key) the metal first, then fill

3) spray etching primer on over the phosphor and then fill

4) sand the tank, paint then fill

any thoughts?

I would go with no.3 Drewps.

I wouldnt really want to remove the phosphor coating.

Spray etching primer, then filler, then prime for paint, then paint.

My reason: = If your tank ever gets a knock the filler usually cracks and falls off. With the etching primer under the filler your tank will still be protected and the phosphor will stay intacted, (till ya get it sorted). The filler (if knocked) usually only cracks away from the last surface it was in contact with.

Try and make sure the etching primer wont react with the phosphor coating.

Thats me thaughts But i am no expert.

how much filler will you have to use? if its a minimal amount ie just deep scratches then why not use filler primer. if its a dent then i would primer first them really rough it up to get the filler to adhere.

I would guess number 3 also Drewpy, and like Chris suggests-a filler primer on top of the etching primer, lead filling with solder is also an option (dunno how this would react with phosphor, although phosphor is widely used in all sorts of metal alloy) if you have any big gaps in seams or golf ball dents :)
