Sorry fellas, don't mean to hijack this thread but since were on the topic I've got mediocre pairs of 3-way towers with the typical vinyl finishes and I'm interested in bringing a little shine and lustre back to them. I'm considering buffing a bit of automotive grade vinyl shine products like detailers and spray wax but they contain petroleum distilates. I'm sure these products will give the finishes the shine I'm looking for but I'm concerned about the long term effects (i.e have seen vinyl dry out or browning over the long run).
Can anyone suggest a good product for vinyl finishes?
