Ever purchase a nicely painted body and then have someone take you out on the first lap causing a crack over your wheel well or worse?  You know it's happened to all of us.  Any way, I purchased a spray can of flex seal clear for a project around the house  and had some left to play with.  As the ad says:

 

  • It’s an easy-to-use, portable, aerosol spray
  • Sprays out as a liquid and dries as a strong, rubberized coating
  • Stays flexible and pliable

 

I took a used retro F1 body with pre-existing cracks , masked off the top of the body and sprayed a couple of light coats to the interior.    I let the body sit overnight to dry.  The body interior surface has a smooth feel to it.  I then bent the body in several directions without creating any new cracks or expanding the cracks that already existed.  In fact, the spray seal seem to strengthen the area where the cracks were already there.

 

The big question:  Did I try it out in a crash yet and how did the body fare?  No, since flex seal won't help you from bending up a chassis in a violent crash.  :laugh2:

How much did it add to the weight of the body?

 

And how much did it effect the flexibility of it?

Unfortunately I did not weigh the body beforehand but any weight gain is miniscule at best.  The body is flexible, not stiff and seems likely to handle a hard crash better than a .10 lexan body without the flex seal spray applied.  If I'm found to be mistaken, I will post here again, or I'm sure someone will let me know  :diablo:

So this is intriguing. With the decline of availability of Parma/Champion rental bodies, we could probably take the .015/.020 bodies that are out there, and spray them with flexseal, tooldip, plastidip, whatever... and make them sturdy enough to manage.

 

I don't have any flexseal, but I have a can of black tool dip. And I have plenty of pretty gnarly bodies to give it a try on.

 

Thanks for the tip!!!

Amazon sells mini flex seal spray cans now.  The shipping will coat you as much as the product but it's still reasonable for those who want to give it a try.

I can't imagine adding this weight to the top of a slot car will help you with handling!  When we can tell the difference in handling from .010 bodies to .007 bodies--putting this on sure can't help.  But--to each his own--if you don't care about that and simply want to save on buying bodies--go for it!  :)

I have for years repair my slot car bodies with automotive silicone sealant, and using tape and in some cases staples some of these bodies I have for over 30 years. I also buy used bodies at the raceway I go to and once they are repaired to me almost good as new.

For body repair I was introduced to Shoe Goo and I have to say, it really works well.  Goes on like "goo", dries to be very light, strong and extremely flexible.  Highly recommended, though, YMMV !

I've used Shoe Goo on body cracks.  If you want a thin coat protection without weighing down or gumming up your body (especially if you are concerned about adding weight on the fast King tracks), flex seal is the way to go.  I brought this idea to everyone's attention as a way of bulletproofing your slot car bodies before you get your first crack. Once tested and if it works, I plan to start using flex seal on the interior of all my bodies before I run my first lap.  A WORD OF WARNING - IT HAS  STRONG FUMES WHEN USING SO I WOULD WEAR A MASK.

actually, this is a dumb idea. you're killing the handling characteristics of the body. it's suppose to be lightweight with side flex; that's where the handling comes from. if the body gets trashed, it's time to throw it out. don't get attach to it, everything dies.

I got a can of that Flex-Seal at W/Mart.  I can see masking a spray conservative amount in specific areas such as the front leading edge of your body and around mounting tube areas.  I'll give it a whirl.  Good idea Tim. :good:
