Epoxy primer works well I use it on anything that's old and rusty , grit blasted rusty chrome wheel rims Epoxy primer then top coat , 5 years no rust or paint lifting , best stuff yet for restoration
Lightly hand sand the Bondo with 36 grit as soon as it becomes firm but not fully cured. It stays sticky on the surface forever but if you knock the sticky surface off and lightly shape it with the 36 grit by hand using a block you will save yourself a ton of time and sand paper. You’ll find that once the sticky surface is removed you can get going with your 80 grit for the next step of sanding and shaping.
Glad you posted this as I'm planning on doing this with the XS2 fenders as the chrome is far too gone and nobody has any used fenders for sale. Just gotta figure out what color I need to do!
One of the things used in the custom Italian bicycle frames that I do is use Bulldog Adhesion Promoter. When a frame has a portion that has a portion that is chromed, the whole frame is dipped. We then mask off the part that is staying chrome and paint the other. We rough it up, as you go through, but then use the Adhesion Promoter. Try is sometime.
I can already tell it's going to look great, the finished result is all down to to the preparation which takes 95% of the time, the final painting takes no time.
@3:30, you feels the surface with thick gloves! You are legend ! If I were there I apply bondo not with standard spatula but a curved plastic or metal piece or a half of pvc pipe which suits the curvature of fender top. Second thing this is too much bondo, man! Remember, less is more. As much you apply more you have to sand.
For less than the price of that sandpaper and expensive primer and paint you could have just bought a hand held sand blaster from Harbor Freight and just blasted it back down to bare metal in a couple minutes and you'd still have it to do other projects.
Don't mix Bondo on cardboard. It can absorb some of the gray filler, and throw off the hardener mixture. Not a dig, just something an older body man told me.
@@urboytony5028 The hardener won't have the same mixture it needs to make the chemical reaction. Some of the needed mixture will be absorbed by the cardboard. The red part of the mixture will be too much, and the Bondo will harden too quickly.
@@yepok2957 oh ok thanks. Makes sense now that I re-read it. I have a little metal plate that I mix mine in for wood repairs at work. Good to know my strive to look professional worked in my favor but I have mixed on cardboard or piece of wood in the past lol.
From everything I read the chrome is very difficult to get paint to adhere to. That's why I scuffed it up good. Fair point. I'm not sure if the epoxy paint would have done well or not on its own. I did get a little carried away with the bondo...it was an experiment. hopefully vibrations don't rattle it all off. LOL
Let me know if you are Missing any random nuts and bolts I've got tons for that bike. Would love to contribute. also if you're missing any other random stuff let me know I may have it
@@KeepOnWrenching haha duude! That's one thing I'm looking for for myself. But I do have a rear grab bar but it doesn't seem to fit on the cl350 I think it's from a CB you may be able to make it work though it's very nice condition.
That looks like two golfballs size bondo which may be the reason it took longer to cure - and by the way that epoxy primer is extremely cancerous good ventilation and a high quality mask required
