Best sanding tips to get my front end sanding down should i just take off the front clip what's the best way to redo that it's got two cracks in it not bad easy fix.

What can i do for that.

I'm planning on getting this done i started half way but think got the wrong sand paper so help would be appreciated.

Please give me tips.

Have a great day

Putting Up a Picture I think i sanded down to much but i still see a little bit of the spider web cracks. Can i keep sanding or no?

Thanks Guys And Girls.

 

Instead of just Clicking on it and not saying anything leave a comment.


Also there is already some chips in the bumper from it So need some plastic filler.

 

Looks feathered backed good, what are the white spots in the middle? I always go by touch before I primer. As long as you don't feel any edges, smooth transition across the fix area.....looks good. Primer and sand again. The real trick will being to get the new paint to blend with the existing.... Good luck! The cracks in the background?

 

those whit spots in the middle are cracks in the bumper little pieces of plastic that fell out. I don't know where or how it happened thats why I'm touching it up.

 

I have been told in the past that spiderweb cracks on urethane bumpers never completely go away, because they are in the bumper and not just in the paint. Although, that part of the bumper is pretty stong and wont flex much, you would be able to get away with just priming and painting. Id bet you could sand the chipped part a little more and 3 coats of high build primer would fill in the rest.

EDIT: If the bumper is cracked that bad that there is plastic chunks falling out, then you should grind them out and fill with plastic repair. Fusor makes a product called #142 extreme bumper repair, ideally this is the stuff to use. Its like flexible glue that will actually stick to the bumper.

If you decide to use plastic filler thats fine to, you just need to make sure you get the right stuff. I think 3m and fusor both make a good plastic filler. But be aware, this stuff doesn't sand anywhere near as nice as bondo or putty. So put it on thin, and it wouldn't hurt to also put a light coat over the spider cracks aswell, to help strengthen it. Absolutely do not just slap bondo or putty on there, it will cause problems.
The plastic filler is usually quite bad for pinholes (little air bubbles in the product that are uncovered sanding), you can apply put a very light skim coat of finishing putty to fill in the pin holes, just try to sand most of it out.

You also should use a primer with a flex agent it it. this allows the flexible urethane bumper to flex without cracking.
I can also still see cracked paint. Sand that out, or the cracks will show right back up.
I assume you know what grit sandpaper to use but just in case. For the bumper glue, Id prep the surface with 80 as well sand it with 80. The plastic filler, same thing.

I wouldnt spray high build primer on anything rougher than 180 grit. It isnt thick enough to fill in a deeper scratch. I use 400 grit to scuff old paint. You need to make sure that you don't spray primer or paint on shiny paint, it will not stick. The surface also needs to be clean and degreased.

I hope this was what you were looking for, if you have any more questions just ask. I would say that a know a fair amount about bodywork but am certainly no expert. So i encourage others to post their input as well.

 

Yup Thanks Also It is looking much better. Gotta do a little more sanding and those little chips you can see in the picture i was thinking about plastic filler.

But what if i got touch up paint and touched it up to fill that in??
Kinda sounds like a bad idea and sounds like it might work there no where deep at all. Almost as thing as a piece of duct tape.

Got more pictures tell me what you think.

Also Tailight Question i got 3/4 of it wraped in 3m tape. Should i wrap the entire thing and also put paper over the areas it isnt getting painted.

 

Some more pics for you guys.

 

I would paint the whole bumper. Otherwise your repair is going to stand out. The right way to do it would be to strip it down, prime it, repair your damage, seal it and paint it. Don't know how ambitious you are or what your skill level is though.
