body filler tips?

I shaved some trim of my 65 tbird, welded the holes with plugs, knocked them in a lil', filled with some bondo. I'm having some difficulty sanding it even with the body line though because there's a slight V in it like a lil' hill. Any tips on sanding it?

Nevermind guys, I got it :] but another question, i dont have the money to primer the whole car, is there any primer that i can use that doesnt cost much to cover it so it doesnt rust for a few months while i do get the money.

NO, there's not a cheap primer that you can use.

Lacquer primer is cheap, but it won't stop rust. The only thing you can do is apply a good coat of Epoxy Primer. It will prevent rust and last a long time.

If you go past the recoat window before you get to paint the car, you will need to scuff it first.

Go to your local body shop supply and buy a 17-1/2 inch sanding board. Also some 150 or 180 grit sandpaper strips.

Sand parallel to the body line, but with the board slightly angled, so the edges of the paper don't make grooves. (The grooves are called block marks.)

If you can't tell how straight it is after "blocking it out", mist it with a different colored paint (this is called a "guide coat").... let it dry... then sand over it again. If there are any low spots, the guide coat will not sand off, because the paper doesn't touch the low spots.

Fill those spots with a thin "skim coat" of body filler or glaze... let it set up.... then guidecoat, and block it again.

As mentioned, use as long of a board as possible, AND For sure use a high quality filler, NOT BONDO

Evercoat Z-Fill is an economical (i.e affordable for someone on a budget) good quality filler. BONDO SUCKS...

I used evercoat on last project.
Evercoat seems pretty nice except I did have some pin holes which was a pain to correct. I found it interesting that the promo made claims about no pin holes. You must use proper mixing technique and hold your mouth just right to avoid pin holes.

On the other hand I painted a car about 15 years ago with bondo and it is holding up fine.

What problems have you had with bondo?

A better filler will sand easier and more even.

For my "good" work I will use Evercoat Gold or Extreme, for casual work I will use the Z-Grip.

The difference for me is in the sanding time and the ability to sculpture the filler down to a nice feathered edge without busting my ***!

I imagine that Bondo will last just fine, but there are better products out there for the money.

IMO pinholes are just something we have to deal with to one degree or another, but the good catalyzed glazing putty sold today makes quick work of them.

May be a dumb question, but why exactly is epoxy primer water proof? I know most 2k surfacers are not but why is epoxy?

Epoxy is the ony true waterproof primer.
that's it's biggest advantage and why it's for bare steel.
Most 2K's are not.


Kirker epoxy primer under $100.00
I've used it and it works fine.
