I thought the issue with silicone based polishes is the perception that the silicones migrate through the gel coat into the underlying structure, making future repairs problematical.
Whether this is actually occurs or not I don't know and am not qualified to comment.

Ever since I watched Shane McCaffery polish his wings with Mr Sheen (!) on the grid each day at the Dalby nationals I have figured it doesn't much matter so long as your repairer has some Prepsol to wash it off with prior to any repairs, which they will always do as a matter of course anyway.

Hello Bernie I use NUFINISH myself and provided you clean the area properly with a product called PREPSOL there is no problem at all with later Gelcoat or PU applications. The cleaning needs to be very thorough and should be done repeatedly using clean rags all the time. I hope this helps.

Hello folks, it's Form 2 time and we plan to give our LS1-f a bit of a buff and polish. A product called NuFinish was recommended, however a quick Google search finds that it contains silicon and I understand that this is not a good thing should any future repairs be required. Is this correct, or is silicon getting a bad rap? Our club has used a Meguiars marine product called M4516 High Gloss Polish, I am led to believe that this contains no silicon but have yet to confirm that. See http://www.meguiars.com.au/productdetail_2006.php?seq=9&category=SPECIALTY&subcat=Marine%20Care&subsubcat=Polish%20and%20Protect&show=3 Can anyone speak with authority on this subject? Any other products that I should know about? The gel coat is in good condition, it was machine buffed last year and shows little if any oxidisation to my untrained eye. I imagine a quick polish followed by a wax would be sufficient, so the Meguiars marine products are looking good: http://www.meguiars.com.au/product_2006.php?category=SPECIALTY&subcat=Marine Care&subsubcat=Polish Thanks, Bernie. ________________________________ _______________________________________________ Aus-soaring mailing list [email protected] To check or change subscription details, visit: http://lists.internode.on.net/mailman/listinfo/aus-soaring
