Thanks to TinTin and his Sealants Summary
thread, I think I have a good idea of which sealants to use where, but I'm still confused on a few of these, and wanted to post a visual reference Q&A for anyone who can offer feedback.
According to the thread
For wheel wells/underbody:
Adseal Premium Quality Sealant Gray
Silkaflex 721 White
Adseal Premium Quality Sealant White
Dicor self-levelling sealant
LoctiteŽ PLŽ S30 Polyurethane Roof and Flashing Sealant
Silkaflex 221 Gray
Parbond Gray or Clear (small hand tubes)
LoctiteŽ PLŽ S40 Polyurethane Window Door and Siding Sealant
Small seams (between aluminum panels)/Exterior Lights
Acryl-R (small cans)
Captain Tolley's Creeping Crack Cure
Based on the above, and from my start on removing the old caulk, I'm going to use Silkaflex 221 Gray on the above my rear and front pano windows.
Should I also use it down the middles as well?
I'm going to also assume that #1 should also be Silkaflex 221 Gray.
Where I'm confused is if #2 is suppose to be Acryl-R or the Clear coat pen folks talk about.
Basically I've been wondering if these are suppose to be caulked or clear coat pen'd (I made up that term.)
