hey guys, I'm working on the new fenders (WITH the vents. ) I got for my 91 T/A vert and I had to bondo a few things, like the vents to the fender since the fit was terrible. As a result, I decided to go for a 1-piece look.

After some sanding though I have a few pits that need to get filled, should I use normal Bondo or the Bondo spot putty?
here's a pic:


and I have a couple very small dents in the fenders as well... regular bondo or spot putty?



^^ you can baaaaarely see it but if you look at the green body filler near the top of the pic, you'll see the dent about 1 inch below it.

AND what's the best way to ensure that the bondo comes out totally smooth? I'm guessing that my only choice is to throw a glossy paint on there to see the lines.

Thanks!

 

You can use either but the body putty is for fine tuning. I have seen people use the putty ( put on too thick) and it looked fine until it shrank. Then you could see it in the body. I would just keep shaping the bondo. A lot of people really put it on thick. That is not really what its for. Its for light filling and definately not for covering rust holes. Just take your time and be patient with it. I am not an expert but I do have quite a bit of experience with it. I always spray a guide coat of cheap paint. The shine from the paint will show any imperfections. Then wet sand it off with some 400 grit paper. The high spots will sand off and you will still see paint in the low spots. Repeat this process until its perfect.

Thats my 2 cents.

Thanks man! The holes are pretty small, but I guess I'll still stick with normal bondo... it'll save me a trip to the auto parts store too lol.

 

spot putty is for exactly that. only for small pinholes and such . its very soft and not good for filling
