Ok, so I've been looking at different tubs for my DIY rack setup and I'm looking for a tub that's a solid color, not clear, and it has to have a lock down lid. Well, I found one at Lowe's that's perfect. Secure lid, solid color and super durable. But there's one flaw that I can't over look...The bottom isn't perfectly flat. Here's a pic.



As you can see, there's about a 1/8" raised portion. I'm going to be using Flexwatt, and I think if I use this tub I would only be heating that raised portion, not the entire warm side. I don't know. I know most of the tubs we use aren't perfectly flat unless it's a V-70 or something similar. So, any suggestions? Also, I'm going for a solid color tub so my BP will feel a bit more secure. Basically I'm shooting for a DIY rack that mimics a commercial rack with ARS solid grey tubs. So, any advice would be appreciated. Thanks!
