Forget vinyl spray on minicell . . .

Hi All;

Some time back I was experimenting with vinyl sprays on minicell foam as a means of "sealing" the fuzz that develops when you sand the stuff. I pointed out that it produced a rough, unusable surface, but that if it was sprayed onto belt sanded foam (like the factory surfaces), it made a nice soft textured vinyl like "car upholsery" finish . . . I promised to report any further developments . . .

Do not even waste your time trying. After a few months I ran across one of my test pieces, and instead of developing pretty wrinkles when you press your thumb into it, it made a nice "pop" and cracked out a thumb-shaped piece every time I tried it. Almost as much fun as popping bubble pack, but disasterous as a suface for minicell. Apparently the vinyl spray gets a lot harder when it cures completely, and shatters at stress seams with the soft foam backing.

I forget the major mfr's vinyl spray I used but I noted it in an earlier post when first starting the tests. Thank goodness I went with Lycra fabric, which does not snap, crackle and pop when I sit in it . . . ;-)

Best Regards, Spidey
