I used McGuires 3 step last year & it looked OK. This year I used some 3M oxidation remover & wax-what a difference. I went over the hull 1 time real good instead of 3 times with nthe McGuires & it looks alot better this year. I'll do the topside after I put it in the water. I've had alot of people tell me that 3M products work better than McGuires.
For the bottom(if you dont have bottom paint yet) pure carnuba is a good way to go...all I need to get it clean at the end of the season was Turtlewax brand wash, and it all came off and was shinny and no discolorization. That wash puts a little wax on so its clean when you un-wrap it in spring. But topside, Jabber, and Smooth are right. Going on my 3rd season and so signs of bottom paint need. K-O-W or F
I have used meguires for years, but this year with my top side oxidized I used a new 3m product. Mike's marine has it in a black round bottle (retail $33.) Imperial compound. It is a combination of finess-it and a compound. I just used meguires yellow wax after and what a difference. Those of you at metro the last three weeks when I was there wheeling know how good it works.
