The Stovebolt Site Forums The Shop Area Paint and Body Shop Preventing Rock Chips or "Stars" On Fenders

I would like some opinions on what the best product is to apply to the underside of fenders to prevent, or try to prevent rock chips from rocks thrown up to the underside of the fenders and other body parts by tires, or whatever. I knew I could get some good opinions here. Thanks!

Geez Joe, you been drivin that '37 round for quite a long
time now, what 'cha been using up till now? Or are you
planning on takin' her down some dark n' dusty gravel roads
in the near future??
If it were me, I'd invest in the applicator gun and
a jug of this:
3m Body Schutz

the 3M stuff is good, and there's a variety of similar coatings available at most FLAPS in 'rattle cans', but what I use is brushable roof seam sealer, which comes 'rubberized' and in fibered grades

NOS front fenders, Denny! The others have been on since 1980. They are in good shape, but need refinishing - no body work, but paint. I came across a set of NOS fronts so I decided to go for it! Ready to put on now, but the backside needs something.

I don't know if it's possible to totally prevent that type of damage. I've had success so far on my '38 by just driving slow when I'm on gravel. We put a rubberized undercoating on the underside of my fenders.

The 3M Body Schutz is what my PPG dealer says to use. It comes in either quart or gallons with an applicator gun OR you can get it in aerosol cans. Aerosol is really the way I am going. It is not the same as automotive paints with hardeners that aerosol cant easily duplicate. The aerosol is the exact same product in every way.

Denny is right yet again. The first time I saw 3m body schutz used I was hooked. It dries hard but remains flexible enough to survive a flex here and there without cracking. My Porsche 911sc rockers and trunk are lined with stuff and painted bright guards red. They look amazing. Just get the $25 gun online and spray it on lightly. It looks like crap if you try and use it to cover up things by putting it on too heavy. I'm doing my 47AD underside in the next few weeks.

Why don't you post a few pictures of the finished product Marko?
Would be nice to see the flip side of the record instead of the
the 'A' side all the time.

I'm with you Denny, I just struggle with the process of linking to my photobucket. I am at a point in my resto where others might like to see, rather than read.

Stovebolt has a photobucket account and they will sponsor your gallery. The other thing you can do is...

I have had my website for about 14 years now, but as of a few months ago, I have a forum with unlimited picture gallery ability. There is no struggle, just upload and everyone can enjoy. It has the ability to show the link here so you can share with everyone here. Of course you have to register, but its free and it has a slideshow built in so people can click thru things easily. forums.devestechnet.com then picture gallery. Glad to help if you run into any snags.

I have to fix a number of PB links and I don't understand the problem people are having. It's actually quite simple. I have a sticky in the ITShortbus forum on how to do it and Dads50 made a video as well. What issues are you having?

We use rubberized asphalt undercoating. You apply it basically by hand or with a putty knife. It works great, no stars and less noise.

And......what would that product be and where might one
find it Colin????

DG

find it all over Denny, the stuff is used in the construction industry for foundation wall coating and roof seam sealing, trowel grade, brush grade, spray grade - cheaper and just as good as overpriced 3M products

Denny, the stuff I'm talking about is for automotive applications and I get it at my local auto parts store. It's called Rubberized Asphalt Undercoating. Giving you a brand name won't do you any good because the stuff I buy is Canadian (I can't remember the name off hand), but if you ask at your local store I think they should have an idea...

Goes on thick and stays flexible, works really good.

Here is a link to my Photobucket.....I hope. Photobucket
