Thick undercoating in a spray can, does it exist?

[Dino]

I need to spray some undercoating behind the front fender where I welded in a patch panel.  Last time I used a spray can of undercoating it was really thin.  I don't suppose anyone makes the thicker stuff in a spray can?  I hate to buy a schutz gun just for the one patch.

 no not in a rattle can , as far as I know!  they are all too thin , what I use to do  , for that sort of job , is ! use a 3m or terrason or wurth or similar spray sealer , ( can even use windshield glue / pu sealer in black ) just out of a normal calking gun ,   squirt sealer out on desired area , use stiff bristle / hair ,  1/2 or 1 inch   brush to work it into any seams etc & cover whole area  , then stipple the whole sealer covered  area with a brush ,  might need to experiment  with brush hair / bristle  length as you go , to achieve , the   sort of look  that matches  ,  once done ,   depending on product MDS , spray rattle can underseal  on straight away or after the sealer sets  ,  would almost always use this method  , on small areas to blend in factory underseal on modern cars etc  was much quicker  than trying to use the correct spray sealer gun , that  one of the other guys have put away blocked up  

(also to use the proper spray sealer gun on small areas  , you  waste more sealer getting the spray pattern correct   & time    )

Can you use the rattle can but do multiple coats ? Let it tack up.

I did find one that was thick in a can but that was many years ago but forgot what it was. But it does or did exist. LEON.

Repeated coats of truck bed liner works OK.

Transtar texture coat works pretty good. Spray it dry and it builds decent. It can be found on eBay.

Rustoleum has a good product, might work for you.

Rustoleum has a good product, might work for you.  I seem to remember that two coats is pretty thick.

Flex Seal in a can, comes in many colors now.

Ha flex seal!   

Tan top I thought about doing exactly that, and I would if I had a bigger area to do.  The Rustoleum didn't work for me, I used it on something else and it's too thin.  I'll give Transtar a shot.

Thanks fellas
