I would buy their parts and assemble myself after seeing this. The various pieces seem ok but the attention to detail of assembly is , well, not very good at all. Look at the pic Conde circled, WTF, sending that out and wiping sealer over the seams they probably didnt even spot weld is crappy and they tack weld the other panels where there should be full welds along the edges, like where tub /cowl/dash mate.
I appreciate the company bringing the availability to the market and the pieces look good, sell the parts and let others assemble, IMO.
Nothing against Topnault at all, great to see new vendors in the space, they make panels/parts well, they seem to have trouble with quality control when assembling pieces together. IMO due to minor changes over years it is very, very , very hard to offer a prebuilt tub that will be right fo rthe application.
