Has anyone here used the Weld-On products for repairing cracks in Vistalites? We picked up a blue and white drum set (pattern F) which has had one crack repaired and also appears to have the seams on one of the top panels reglued as well.

I'm still taking it apart to assess whether it's usable or not but looking to some buy Weld-on product to possibly fix/reinforce the existing repairs based on information at VintageDrum.com. They reference Weld-On 3, 5, and 10 but it looks like they no longer make 5 and 10 and that perhaps they've been replaced by 4 and 16 (or at least 16 as 4 doesn't seem much different from 3).

If you've done any repairs, could you tell me which product you've used and for what type of repair, how much you used and what type of repair it was (length of crack?). I'm assuming a little goes a long way. Also, if you could tell me where you purchased it that would be great. I'm looking at TAP Plastics right now.

Thanks for any help you can give me!
