New Glass

We will see where this goes. I'm tired of buffing and waxing the stripes etc. with little durability. On the prep side I've run the gamut using all the marine grade polishing compounds + a number of 3M marine grade grinds of compounds. Up to that point the results are pure shine. I used several of the leading marine wax/polishes with the exception of Collinite. Same results after 4-6 weeks, oxidized stripes.
This time around I'm giving New Glass a run. I called them Wed and had a great discussion with their support staff. Their recommendation is to use soft scrub for stains and polish the stripes. He stated clearly colors are the issue ie. blue hull or black stripes as both tend to oxidize at a greater rate and depth than the white. He recommended that the colors must be polished to remove the oxidation. You do not have to polish to a high gloss as New Glass will provide the gloss. It is very important to remove all oxidation as New Glass forms a chemical bond with the gel coat where as wax / polishes form a mechanical bond and therefor never alter the gelcoat on a chemical basis.
So I'm prepping the surface by washing normal dirt and stains with soap and water, wipe down. Next rinse the surface and then buff/compound with random orbital buffer until black stripe oxidation is remove and color is pure. I'm buffing with either soft scrub or 3m cutting cream. Spray on New Glass cleaner then scrub with pad/sponge. Wash with water and towel dry to remove water spots. Next wipe on 4-5 coats New Glass. Wait approximately 1-3 minutes between coats. Done.
The boat will sit outside on the trailer until mid-Oct. So I will keep you posted on oxidation levels.
FYI streaking has not been an issue as New Glass is very low viscosity. Also I wipe each coat in a different direction of travel rotating 45' between application direction. There is some shrinking of the film during drying which also provides some leveling.
The gloss on the port side so far is excellent.
There doesn't appear to be any significant color influence from New Glass after 5 coats. The white color has a very slight warm cast which I believe is primarily due to the reduction in specular reflection of the surface and actually more toward the slight warm white of the original color coat during mfg.
Fingers crossed!
