Fuel Tank Dents, filler

Can anyone recommed a good filler, I have a few small dents in the fuel tank and can't get to them the push them back out. Do I need to take it down to metal to use the filler? Or can I leave some primer? Thanks Donho

 

3M makes a spot putty metal filler that I get from Advance Auto Parts. It has worked for me on numerous occasions.

 

Bondo. And yes, take it to the metal.

 

Bondo is love, bondo is life.


Sand it all the way down, clean with acetone for good effect, and then lay the bondo on thick. Sand, contour, finish sand, seal, prime, paint.

 

I'll be working on it this weekend thanks for the great advise, this site is awesome, Donho

 

I'm sorry, did someone say Bondo?



The red is actually Bondo Glazing and Spot Putty, applied after all the Bondo was sanded to fill the very small pinholes that develop, instead of having to sand more damned Bondo off the tank.

It's been over a year since I did my tank, and the thought of it still hurts my sanding muscles.

Oh, and CAUTION CAUTION CAUTION
Make sure you drain the tank and let it COMPLETELY air out the fumes for AT LEAST 24 hours before you start sanding on that sucker. We've had more than one member lose some arm hair because of the static electricity generated during sanding igniting a spark to the tank, and that in turn igniting the fumes, which are actually the flammable part of petrol.

 

Thanks for all the great info, I still have my arm hair and the tank is very happy now. Bondo and glazing putty worked great. Donho

I,m thinking about Copperhead Metallic Paint for the tank, side covers, and a few other parts.
