Accumulator said:I have zero experience with Ultima (and I don't use Zaino myself) but I have it on reliable authority that Zaino does *not* cause problems like that. My best painter uses and recommends Zaino, and he's not the kind of guy to make his job harder
IME only the nastiest of cheap silicon products cause problems. I've simply *never* had my LSPs penetrate to the point where my body/paint guy encountered a problem. Even the silicon containing older version of 3M Showcar Paste Wax cleans off with no problem.
Interesting...
The only product I've ever heard of that has caused some people grief with repainting oddly enough was Meguiar's #20 Polymer Sealant.
