Bubbling paint on bonnet (hood)
Sep 04 2011
There are numerous posts about paint "bubbling" but the ones that I have read refer to the problem ocurring at the edges of the bonnet.
I have some tiny, i.e. 2mm stone chips that have threads appearing under the paint that direct away from the actual stone damage.
So far my solution has been to use a glass fibre pen to scrape away all paint layers to reveal the tiny corrosion point on the aluminium. I then carry on gently scraping along the track of the thread (bubble?) until I'm happy that I have eliminated the corrosion area.
The above process is heart breaking as the rest of the bonnet is perfect.
Of course the resulting repair process is equally disheartening because of the Galaxy Grey mica paint variation. I immediately fill with grey primer. Then use 2500 grit SC paper to flatten then use Mazda paint stick brush. Using paint leveller after this is a lottery result. Leaving base coat without clear coat too long also risks metalic particle oxidation.
Just looking fo sympathy!!!!
