1997 Rear fender well repair
Hi all,

 My dads U320 lost a right rear airbag during travel and destroyed the upper well area. After reading some old post we have decided to cover the damaged area with the 3M 5200 product and install a piece of stainless to further protect the...

Longer screws might open up a can of worms. Maybe us a stud finder to be able to use short screws. If the area was cleaned up the 5200 is about as strong as you are going to ever need.

You might try using some large head 3/16 aluminum rivets, about 1/4" long

Thank You both for the reply's.  That is what I'm afraid of putting longer screws into wires, pipes etc and not knowing until it's too late. I will have a talk with Dad about eliminating the stainless and just using the 5200 as a cover. The tire...

You can still use the stainless with one of the good adhesives.

I will take the advice given and go the other route.  Stainless only no screws.

Next Question:  I applied a layer of 5200 already to the wheel well area and it's almost dry. This 5200 is the multi day drying type.  Can I reapply another layer of...

I can't find any information that would prevent you using another layer and putting the stainless on. Use something like jacks and wood to press it up tight until it drys.

Yes Sir will do.  I just call 3M and talked to the adhesive division. I went thru what I already applied and gave them your idea and they said the stainless will adhere without issue. They did recommend using a scotch brite pad to give the...

I just finished mine. I used Henry's roof mastic to fill the hole and then had a local plastic company cut 1/4 inch x 2x2 foot pieces of abs. I then drilled 8 holes in the abs perimeter, purchased large head 1 inch screws, bought the extra hold...

Anyone see a tire cut risk if tires contact metal above tire? Now there is no metal around tires.

That's why I used plastic. I think metal is concerning

That's why I used plastic. I think metal is concerning but i/4 inch plastic jammed could probably cut a tire as well

Thin sheet stainless bonded with 5200 would just wear through if the tire rubbed in my opinion.

Wear though with a sharp edge?

Re: 1997 Rear fender well repair

Without it actually happening it is pure conjecture whether the beveled edge would remain bonded to the 5200 or become loose and create a sharp edge hanging down. As I posted my opinion ymmv.

Update on repair:

Want to confirm that the 5200 will bond to a cured application of 5200. We lightly scored the first layer as recommended by 3M and then applied a complete heavy covering of the 5200 to top side of the stainless. I'm sure I used...
