Bedliner spray on wing undersides

Anyone try using Duplicolor's truck bedliner spray for the undersides of their wings? At $11.99 per can it looks like a great deal instead of getting a professional spray. Just curious because my dad and I just used some to cover the bottom of a aluminum boat to help seal the leaky rivets. It would also allow you to put whatever thickness coating you prefer.

I used spray can liner (some stuff from the auto store) on the rear wings and it is kind of O.K. but not as thick and rubbery as I have seen with the pro liner. After a few years it tends to flake off in some places, but that may have been the insufficient surface prep.

 

On my Birkin the GFRP is rather strong and the liner has more of a cosmetic purpose. I know that the thinner shelled Caterham wings are more prone to star cracks on impact and a durable thick liner may be better. On the other hand the thick liner will defeat the weight saving purpose of the thin wings......

 

Did anyone invent a flexible wing made of rubberized material yet? That would solve the problem with autox cone damage too ;-)

In fact, the autox cone material is just perfect for that purpose :D

 

I wonder if I can drag a few away under my car and make some fenders with them

I suppose someone could make a urthane copy of the wings. It might flex too much at higher speeds and rub the wheels.

 

I hoped I prepped the aluminum on the boat well enough. Used an angle grinder w/ a 60 grit flap style sandpaper wheel. It was a pain to sand around all the rivets. Pro liners spray a lot more material than a spray can so another can or two would make it thick enough. You could also just use a roll on bedliner.
