Tbh, t-cut is what you want. Make sure you use it a few times and put some pressure on the cloth. It's probably the best stuff for building up protection on paintwork.
FFS.
SRP is not a layering product. Egp and waxes are.
SRP is a polish, hence the name Super Resin POLISH. Use this once, then buff off the residue. Then apply thin coat of EGP, wait for it to haze (hour/longer the better), then buff off with a micro fibre. Then add another layer, same method. This can be done anything from 3-6 times.
Buffing pads, no harm. Don't like doing it as there is the possibility to push too hard and remove the sealent. But a finishing pad still has a minute amount of cut, so could well have taken off your sealent/LSP.
Just get off your arse and use some elbow grease
