Sound Insulation

I have seen several posts about stick on sound insulation but haven't seen any on spray on. I have used Lizard Skin in the past for both sound and heat insulation with good results. Has anyone used this on an SL-C and were there any issues?
I have used them both on my SLC and have no problems to report. Can not tell you if it's quieter or not, but certainly easier to apply over large areas. I did the entire tub and interior areas for noise and heat where required.
Thanks Dan. That was my thought - spray the tub early in the build to minimize the need to mask anything off. Will also do the inside of the doors and the body around the cooling/heater hoses. I already have the sprayer for it so only have to buy the materials.
