I intend to get my original '51 plunger tank re chromed & painted,
it has a very small dent where indicated, ( about the size of a 5 cent piece)
I have been told by the painter to get it sand blasted to remove all the old chrome,
then re chromed prior to painting... (dent would pull out prior to painting..)
I have also been told of a person who may be able to re roll the tank, (removing the dent)
then re chromed & painted..
I have also been told to leave it, that the chromers should be able
to remove the old chrome & fill the dent prior to re chroming...
any advise from those in the know would be appreciated.. *dunno*
Cheers WozzA

The only repair tht will not show trough te chrome is to have the dent knocked out.
If filled it will have to be steel and you can not fill a dent with weld that still has chrome on it

I had a large but shallow dent on the upper painted surface of my A10 tank. I managed to tap most of it out with heat and a home made tool leaving only ripples. After the tank was heavily coppered to fill rust pitting, polished and chromed I asked the paint man to roughen the area of the ripples and fill with body filler before painting the tank with two-pack, (leaving the side panels chromed, natch). The ripples do not show and after three years, so far the filler has stayed in place.
Later: Ah, I see that your tank is almost a negative of mine that has chrome side panels, where yours are painted and the rest is bright. Maybe you could consider changing the colour scheme; that would allow you to hide the dent repair under paint.

small dents can be filled with brazing dressed of and polished ready for re- chroming

The chromer will de-chrome before polishing and plating. Dent con be filled with lead but as Trev said anything will show through the chrome. I had my tank lead wiped and if you looked close the wiped sections appeared slightly off colour.

Don't get it sand blasted, Woz, speak to the plater first. They will strip the tank and polish it to a high standard. I would go with someone who will do the repair. One that small could possibly be filled with silver solder but would have to be done carefully to avoid distortion.
Probably the best way is to have the plater strip the tank and get someone to open the tank bottom and beat the dent out.

Wozza, I had my tank repaired by John Bennet from Kinglake West. He removed the base and repaired what was a fairly battered tank which was then chromed. I can recommend his work. If you want his contact details message me.

Sandblasting can generate a lot of heat, hence distortion in thin sheet metal. No way would I do that to a vintage gas tank. Surely the platers can chemically strip it.

Thanx Mark.... thats the guy I was told of... I've got his number... *wink2*
I'll take it to the chromers & see what he's got to say...
