Good evening! I would need tips for 2 things. 1. I have a Fautras horse hanger, completely made of GRP, which is painted with an unknown color (versm. synthetic resin) and needs a new color dress. If I grind the current paint properly and then apply a 2k primer (epoxy) and put on it e.g. a single component hammer coat? the hanger stands under the roof and is therefore not exposed to the weather all year round. 2. I am building a BMW K100 new and got my aluminium tank really well defined by a carossier company. a few tenths of a millimeter, however, I also have to spat. goes there normal carossier lease? adheres to the Alu? then probably again the 2k primer as a basis for then a 2k-Nitrolacki in Uni-Black. Is this then enough gasoline festival, if you clatter? As equipment I have water-free air and 2 SATA pistols available. Thank you very much!
