Hey nick
I know this is an old thread but why not work on it to try and get the paint as good as can be expected.Also you can consider this a learning experience/curve so when you get another DD you will know just what and how to accomplish it for a great detail, not to mention a better detailer!
The first thing I do on something I'm unsure of is use my craftsman twin tripod halogen worklight to get the most light on the surface and check as good as possible ( I even use my brinkmann dual xenon light and my carson 10X lumiloupe to check on an area I may have questions about)
Next after a complete wash or two I will then use a cleaner (swirl & haze remover with the orange pad) also in your post you never said how many applications you did with the SHR ( sometimes 1 application isn't enough it offten times takes 2 to 3 applications)also the most important step to any detail is the cleaning step, the more time you spend in this step will reflect your outcome IE:deepth of shine-clarity-reflectivity(on a darker paints)and something were all after that swirl free soaking wet look!
Anyways after you've done your cleaning step, then go to your claying because if you just clayed first on such a neclected surface your going to be loading-up that piece of clay pretty fast and before you get half way through your piece of clay will be trash(no matter how many times you kneed it into itself and pick out all the trash out off it) And for this reason it's so important for this step in a neglected paint.
Now you've removed all the above surface bonded contaminants you need to go after the contaminants thats in your paint so go back to your SHR and do another 2 or 3 applications, when you get this far you will see what I'm talking about.(Don't know if this is a Single stage paint on your S-10 but if it is you will be smiling pretty good now)
Now let's bring some life back to that paint by applying some polish, (adams fine machine polish using the white pad) because overtime direct sunlight and the exposure to outdoor environments has takin away the resins (oils) from your paint and need to be replenished back into the pores of your paint to bring out the glossy and great reflectivity, More or less it's like lotion for your skin but it's polish for your paint just work it in and a healthier paint will appear!
Now after all the hard work comes the time I look forward too! applying and locking in all that beauty, each person is different and what they like but to me there's nothing like applying 2 thin coats of a paste wax, sometimes when I feel energized I will apply a thin coat of a sealant and try to wait atleast 30 minutes or if I don't have to drive it or need it I will wait until the next day for the sealant to cure and then apply a thin coat of the paste wax and then wait at least an hour or so and apply another thin coat of paste wax. I know it's sometimes is a heated topic about layering but in MY OPINION more then 3 applications of any wax liquid or paste is it I see no change in the shine or gloss, but it all comes down to what looks good in your eyes because it's your paint and you know what looks good to your eyes.
Anyway getting long winded sorry! but talk about a deep wet looking shine that will blow your mind, My mustang has/had the same problem with the bubbling on the back driver-side quarter for the last 10 years (garaged kept for at least 6-kids took over my garage! LOL) anyway I would use painters tape to tape off around that area since I tape off all trim and moldings anyway so my pc wouldn't hit it and I would do that area by hand very lightly.
Hope I've been of some help:thumbsup:
