Well I've begun testing all of my polish brands (including my own) on an ex japan race car (MGF)
We have about six of them here at the shop which will be turned into oz spec race cars
This one is a nice red and after polishing would look like rich tomato sauce
I have got einszett, menzerna, opt, aussie gold (terrific local brand with worlds best QD), sonus sfx, magnum top gear, duragloss, wolfgang, fire glaze, glare, farecla, dinitrol (swedish), pinnacle XMT, Driven to perfection (small CA company) and some others as well
After washing and claying, I divided the far right side of the hood into four 1 x 1 foot sections and decided to use LC orange, white and black 4 inch pads with all products (got three sets of CCS 4 inch) and washed them by hand once used (so not to contaminate one brand with another)
Paint had some scratches and medium swirls and on the first one, OHC with orange and OP with white pissed them all off and left a very bright and fairly wet gloss. I love how long these work. Probably has alot of parrafin oil and glycerin
Finished off with driven super polish for a super high gloss wet look and paint was flawless.
Next was sonus SFX 1 V2, SFX 2 V1 (old formula that I've added some glycerin too) and SFX 3 V2
Paint was definately richer and darker than Optimum and again, flawless
Menzerna came out next. 91L Intensive (orange), 106FF (white pad and worked for ages with some aussie gold showroom glaze on the paint to stop it drying)
That process provided an even richer candy apple red colour and the best clarity of the lot but not quite as wet)
Paint was completely perfect
Alongside the menzerna was my Scratchinator range
Scratch banish, Swirl Abolish and Zero DFX glaze
These have a long working time and provided the best colour richness (maroon red instead of the tomato sauce look of the other three)
The wetness, depth and clarity was also the best of all.
Finally, Prima Swirl got stuck into some deep wet sand scratches on plastic bumper with LC orange pad at 1500 rpm and back down to 900 and 700 rpm. the colour enhancement and wetness of that alone was so good it was LSP ready and flawless.
I'll take some pics of these for you.
So after that, Optimum is definately back in my good books but I would love david to make a stronger levelling compound
perhaps 600 to 800 grit
