Appreciate some opinions on the body filler you use. Picked up a race car thats got a lot of rust comming through faily thick bondo. Going to grind out the bad spots, skuff up the rest and paint. Thanks!

Rage Gold

I have been useing the

Dynatron Dyna-deLiight body filler

also use the all metal to fill trim holes and skim coat it with the filler

Can never go wrong with Rage Gold from Evercoat or their Extreme filler, it spreads like butter and sands like drywall mud,but it costs around $55 a gallon

And worth every cent compared to the cost and aggravation of clogged sandpaper using the cheap stuff.

the paint supply shop near my house has their house brand, it runs down the same line as rages does, but its 15 dollars cheaper a gallon.
metal to metal is great stuff too for a first pass.
