First I'd like to thank you guys, I've picked up a lot of good advice here. Lately I've been getting a few tanks off of old wrecked bikes...I've started doing some of the bondo work and i shut down operations untill i hear back. I get the mud perfect, sanded smooth and feather the edges.with 200, 400, then 600....then i painted...I can still see the patches........What do i do it's smooth as owl shit and even more so after i cleared it. but the patches are still visible at certain angles. I want them to look new, Help?

Sound to me like you didn't extend the Bondo far enough past your dents or the edges are not featherd well enough. If you have a good sized dent you may have to extend past the dent 3-4". Did you sand using your hand or did you use a block to sand with. If you can see the patches then its not as smooth as you thought. If you guide coat on your primer then you can see where your edges are and it will help you get a smooth surface. It takes a real soft touch to feel an edge thats why you should guide coat before the base coat. I'm sure there are better ways but that's how I do it. You can also use a stud welder to reduce the size of a dent and use less Bondo.

hey I'm using rattle cans......It's my sons mini chopper...It's my first....guide coat???? No primer...The patches dissapeared after 3 good coats,since i was working with rattlers really 9 coats i like to keep them thin and I wet sanded with 600 between each coat, 4 coats of clear and sand, masked it off flammed it with a contrasting red, misted with gold...stipped the tape, and smoothed the edges, then put 12 thin coats of clear....I'm working on rotten shoestrings here so cut me some slack about the rattlers.....My son's gonna love it and It's saved me tons of money...I just graduated in february and there's not much in the sugar jar yet... I'll post some photo's of the project tomorrow.....I've got to box it all up tomorrow for safe keeping...Then I'm goning to start the framework ......bending, cutting and welding...

If you do any further paint jobs, you really want to make sure you lay down some primer after you have sanded your filler. This will seal the filler and it will also give your paint much better coverage so you won't need so many coats of paint.

Ripp[/QUOTE If you prime the tank in a light grey, use a dark color (I use black) to dust a thin "Guide" Coat of paint over the primer so when you block sand it, the places that are still dark are low spots. You want to use a block of wood or foam to "block" sand with to keep your fingers from making ridges in the filler, and to show you where you need to add filler. High build or filler primer can also help fill small imperfections. Duplicolor sells a Sealer primer which also helps keep the filler work from ghosting or showing through. Fill, guide coat, block sand, Repeat till you leave no black, then sealer primer,sand and paint. It takes a little more time, and money, but you end up with a better job, and happier customer.
